bd937497ea Consistently use device_t
Several files use the internal name of `struct device` instead of
`device_t` which is part of the public API. This patch changes all
`struct device *` to `device_t`.

The remaining occurrences of `struct device` are those referring to the
Linux or OpenBSD version of the structure, or the code is not built on
FreeBSD and it's unclear what to do.

27b134f016 Remove rge driver from Broadcom XLR
nlge(4) is supposed to deprecate rge(4) for Broadcom XLR when it was
introduced 5 years ago.

rge doesn't build on -CURRENT due to MII changes. All the XLR kernel confs
use nlge. Let's get rid of the old driver for FreeBSD 11. We can use
10-STABLE or SVN to go back and look at the old driver if needed.

d8cc52c9a1 Mechanically convert to if_inc_counter(). 2014-09-19 09:19:49 +00:00

b245f96c44 Since 32-bit if_baudrate isn't enough to describe a baud rate of a 10 Gbit
interface, in the r241616 a crutch was provided. It didn't work well, and
finally we decided that it is time to break ABI and simply make if_baudrate
a 64-bit value. Meanwhile, the entire struct if_data was reviewed.

o Remove the if_baudrate_pf crutch.

o Make all fields of struct if_data fixed machine independent size. The
  notion of data (packet counters, etc) are by no means MD. And it is a
  bug that on amd64 we've got a 64-bit counters, while on i386 32-bit,
  which at modern speeds overflow within a second.

  This also removes quite a lot of COMPAT_FREEBSD32 code.

o Give 16 bit for the ifi_datalen field. This field was provided to
  make future changes to if_data less ABI breaking. Unfortunately the
  8 bit size of it had effectively limited sizeof if_data to 256 bytes.

o Give 32 bits to ifi_mtu and ifi_metric.
o Give 64 bits to the rest of fields, since they are counters.

__FreeBSD_version bumped.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.

- Also while at it, use __FBSDID.

8e5d93dbb4 Convert the PHY drivers to honor the mii_flags passed down and convert
the NIC drivers as well as the PHY drivers to take advantage of the
mii_attach() introduced in r213878 to get rid of certain hacks. For
the most part these were:
- Artificially limiting miibus_{read,write}reg methods to certain PHY
  addresses; we now let mii_attach() only probe the PHY at the desired
  address(es) instead.
- PHY drivers setting MIIF_* flags based on the NIC driver they hang
  off from, partly even based on grabbing and using the softc of the
  parent; we now pass these flags down from the NIC to the PHY drivers
  via mii_attach(). This got us rid of all such hacks except those of
  brgphy() in combination with bce(4) and bge(4), which is way beyond
  what can be expressed with simple flags.

While at it, I took the opportunity to change the NIC drivers to pass
up the error returned by mii_attach() (previously by mii_phy_probe())
and unify the error message used in this case where and as appropriate
as mii_attach() actually can fail for a number of reasons, not just
because of no PHY(s) being present at the expected address(es).

- Move RMI MIPS extension to atomic increment word (LDADDWU) to common
  header file sys/mips/rmi/rmi_mips_exts.h
- Fix xlr_ldaddwu() for 64 bit, it is a 32 bit operation, use

- Provide dummy xlr_enable_kx/xlr_restore_kx for n32 and n64.
- Provide xlr_paddr_ld() instead of xlr_paddr_lw(), so that the
  descriptor formats are same for 32 and 64 bit
- update nlge and rge for the changes

These changes are also needed by the security driver which will be
added later.

8f8ae306c6 nlge (alternate XLR GMAC driver) updates:
- Updates for the message ring clean up in r212321.
- Instead of dropping Tx packet on credit fail, retry send until it
  succeeds.
- Fix freeing mbufs in case of P2P descriptors:
  We cannot free the mbuf when the P2P descriptor freeback is received. The
  mbuf may be still in use by the GMAC, since the P2P freeback indicates that
  it read the P2D descriptors in the P2P message.
  Now we free just the P2P descriptor when the P2P freeback message is
  received.  Another freeback P2D message has been added to the end of
  the packet descriptors, the mbuf will be freed only when we received
  this.

The P2P descriptor issue was reported by srgorti at netlogicmicro dot com.
