o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
- Merge generic flow control advertisement (which can be enabled by
passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care
mask" but instead as a media specific option this. This has the
following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in
the PHY specific implementations).
- Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
not applicable there.

o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
- Merge generic flow control advertisement (which can be enabled by
passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care
mask" but instead as a media specific option this. This has the
following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in
the PHY specific implementations).
- Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
not applicable there.

o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
- Merge generic flow control advertisement (which can be enabled by
passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care
mask" but instead as a media specific option this. This has the
following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in
the PHY specific implementations).
- Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
not applicable there.

o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
- Merge generic flow control advertisement (which can be enabled by
passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care
mask" but instead as a media specific option this. This has the
following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in
the PHY specific implementations).
- Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's

these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in

o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.

o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control

IFM_FLOW isn't implemented as a global option via the "don't care

being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE

from the `ifconfig -m` output
