5a13764b11 Change xl_rxeof() a bit to return the number of processed frames in
RX descriptor ring. Previously it returned the number of frames
that were successfully passed to upper stack which in turn means it
ignored frames that were discarded due to errors. The number of
processed frames in RX descriptor ring is used to detect whether
driver is out of sync with controller's current descriptor pointer.
Returning number of processed frames reduces unnecessary (probably
wrong) re-synchronization.

While here, remove unnecessary local variable initialization.

1dcad8ec9a Set the initial value of maxfilesize to OFF_MAX in the
new NFS client. It will then be reduced to whatever the
server says it can support. There might be an argument
that this could be one block larger, but since NFS is
a byte granular system, I chose not to do that.

78e4b1f838 Change the new NFS server so that it returns 0 when the f_bavail
or f_ffree fields of "struct statfs" are negative, since the
values that go on the wire are unsigned and will appear to be
very large positive values otherwise. This makes the handling
of a negative f_bavail compatible with the old/regular NFS server.

47ff47a858 Don't perform NF calibration for radio chains which aren't in use:
Quoting the ath9k commit message:

At present the noise floor calibration is processed in supported
control and extension chains rather than required chains.
Unnccesarily doing nfcal in all supported chains leads to
invalid nf readings on extn chains and these invalid values
got updated into history buffer. While loading those values
from history buffer is moving the chip to deaf state.

This issue was observed in AR9002/AR9003 chips while doing
associate/dissociate in HT40 mode and interface up/down
in iterative manner. After some iterations, the chip was moved
to deaf state. Somehow the pci devices are recovered by poll work
after chip reset. Raading the nf values in all supported extension chains
when the hw is not yet configured in HT40 mode results invalid values.

d2615832bf Fix up the chipset checks for the AR5416 and later silicon.
The checks should function as follows:

* AR_SREV_<silicon> : check macVersion matches that version id
* AR_SREV_<silicon>_<revision> : check macVersion and macRevision match
    the version / revision respectively

* AR_SREV_<silicon>_<revision>_OR_LATER: check that
  + if the chip silicon version == macVersion, enforce revision >= macRevision
  + if the chip silicon version > macVersion, allow it.

For example, AR_SREV_MERLIN() only matches AR9280 (any revision),
AR_SREV_MERLIN_10() would only match AR9280 version 1.0, but
AR_SREV_MERLIN_20_OR_LATER() matches AR9280 version >= 2.0 _AND_
any subsequent MAC (So AR9285, AR9287, etc.)

The specific fixes which may impact users:

* if there is Merlin hardware > revision 2.0, it'll now be correctly
  matched by AR_SREV_MERLIN_20_OR_LATER() - the older code simply
  would match on either Merlin 2.0 or a subsequent MAC (AR9285, AR9287, etc.)

* Kite version 1.1/1.2 should now correctly match. As these macros
  are used in the AR9285 reset/attach path, and it's assumed that the
  hardware is kite anyway, the behaviour shouldn't change. It'll only
  change if these macros are used in other codepaths shared with
  older silicon.

489eeba940 T4 packet timestamps.
Reference code that shows how to get a packet's timestamp out of
cxgbe(4).  Disabled by default because we don't have a standard way
today to pass this information up the stack.

The timestamp is 60 bits wide and each increment represents 1 tick of
the T4's core clock.  As an example, the timestamp granularity is ~4.4ns
for this card:

# sysctl dev.t4nex.0.core_clock
dev.t4nex.0.core_clock: 228125

8820ce5fe7 T4 packet filtering/steering.
- Enable 5-tuple and every-packet lookup.

- Setup the default filter mode to allow filtering/steering based on IP
  protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match
  type; all combined together.  You can also filter based on MAC index,
  Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll
  have to modify the default filter mode and exclude some of the
  match-fields in it.

  IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter
  rules.

- Add driver ioctls to get/set the global filter mode.

- Add driver ioctls to program and delete hardware filters.  A couple of
  the "switch" actions that rewrite Ethernet and VLAN information and
  switch the packet out of another port may not work as the L2 code is not
  yet in place.  Everything else, including all "drop" and "pass" rules
  with RSS or absolute qid, should work.
