PCB, simply embed it in the PCB, avoiding additional memory overhead,
memory allocation overhead, and removing one of the few remaining
uses of dtom() in the network stack.
Restore misplaced spx_ctlinput() from an earlier commit.

severe silicon bugs that can't handle VLAN hardware tagging as well
as status LE writeback bug. The status LE writeback bug is so
critical we can't trust status word of received frame. To accept
frames on Yukon FE+ A0 msk(4) just do minimal check for received
frames and pass them to upper stack. This means msk(4) can pass
corrupted frames to upper layer. You have been warned!
Also I supposed RX_GMF_FL_THR to be 32bits register but Linux
driver treated it as 16bit register so follow their leads. At least
this does not seem to break msk(4) on Yukon FE+.

Yukon FE+ is fast ethernet controller and uses new descriptor
format. Since I don't have this controller, the support code was
written from guess and various feedback from enthusiastic users.
Thanks to all users who patiently tested my initial patches.
Special thanks to Tanguy Bouzeloc who fixed critical bug of initial
patch.

The GM_GP_CTRL register may have stale content from previous link
information so clearing it will make hardware update the register
correctly when it established a valid link.
While I'm here remove stale comment.
does not guarantee established link. Also 1000baseT link report for
fast ethernet controller is not valid one so make sure gigabit link
is allowed for this controller.
Whenever we lost link, check whether Rx/Tx MACs were enabled. If both
MAC are not active, do not try to disable it again.
mark controller's capability. Controllers that have jumbo frame
support sets MSK_FLAG_JUMBO, and controllers that does not support
checksum offloading for jumbo frames will set MSK_FLAG_JUMBO_NOCSUM.
For Fast Ethernet controllers it will set MSK_FLAG_FASTETHER and it
would be used in link state handling.
While here, disable Tx checksum offloading if jumbo frame is used
on controllers that does not have Tx checksum offloading capability
for jumbo frame(e.g. Yukon EC Ultra).
FE+ controller. Due to the severe silicon bugs for Yukon FE+,
88E3016 seems to require more workarounds. However I'm not sure
whether the workaround is PHY specific or only applicable to Yukon
FE+. The datasheet for the PHY is publicly available but it lacks
several details for the workaround used in this change. The
workaround information was obtained from Linux. Many thanks to
Yukon FE+ users who helped me add 88E3016 support.

advertisement register. Some PHYs such as 88E3016 requires NEXT
Page capability to establish valid link. Also set protocol selector
field which is read only but it makes the intention clearer.
is valid only for auto-negotiation case so check the bit if we know
auto-negotiation is active. While I'm here explicitly checks
current speed with speed mask and set IFM_NONE if resolved speed
is unknown.
checks extended status register to see whether the PHY is fast
ethernet or not. This removes a lot of checks for specific PHY
models and it makes easy to add more PHYs to e1000phy(4).
While I'm here remove setting mii_anegticks as it is set with
mii_phy_add_media().
ReleaseLockOwner operations analagous to what is already
in place for SetClientID and SetClientIDConfirm. These are
the five NFSv4 operations that do not use file handle(s),
so the checks are done using the NFSv4 root export entries
in /etc/exports.

Remove PAGE_SIZE alignment used in Rx buffer DMA tag creation. The
alignment restriction was used in old local jumbo allocator and
nfe(4) switched to UMA backed page allocator for jumbo frame.
This change should fix jumbo buffer allocation failure.

to it for the client side reply. Hopefully this fixes the
problem with using the new krpc for arm for the experimental
nfs client.

where a client is not allowed NFSv4 access correctly. This
restriction is specified in the "V4: ..." line(s) in
/etc/exports.
Approved by: kib (mentor)
on platforms with strict alignment requirements. In particular, this fixes the
problems with the new RPC transport on the arm platform.
Note: this adds yet another copy of nfs_realign(). I will attempt to refactor
after NFS_LEGACYRPC is removed.
