c88fa71928 cxgbe(4): Update T4, T5 and T6 firmwares to 1.16.26.0. Changelog for
all public firmwares for all chips since the last release (1.15.37.0)
follows (it's a straight copy-paste from the Release Notes for the
12/30/2016 Unified Wire release on Chelsio's website).

T6 Firmware
++++++++++++

Version : 1.16.26.0
Date    : 12/28/2016

-----

BASE:
- Max number of egress and control queues adjusted to accomodate
  co-processor mode queues.
- Fixed intermittent DDR3/4 ECC errors.
- Fixed a traffic stall when ETS BW is configured as 0%.
- Max number of ethctrl queue in VF set to 1.

ETH:
- Added a new config file option 'speed' under port section to set the
  port speed.  Use only when auto negotiation is off.
- FEC option removed from firmware config file. cxgbtool can be used to
  change the fec setting.

6af45170c1 Chelsio T4/T5 VF driver.
The cxgbev/cxlv driver supports Virtual Function devices for Chelsio
T4 and T4 adapters.  The VF devices share most of their code with the
existing PF4 driver (cxgbe/cxl) and as such the VF device driver
currently depends on the PF4 driver.

Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf
PCI device driver that attaches to the VF device.  It then creates
child cxgbev/cxlv devices representing ports assigned to the VF.
By default, the PF driver assigns a single port to each VF.

t4vf_hw.c contains VF-specific routines from the shared code used to
fetch VF-specific parameters from the firmware.

t4_vf.c contains the VF-specific PCI device driver and includes its
own attach routine.

VF devices are required to use a different firmware request when
transmitting packets (which in turn requires a different CPL message
to encapsulate messages).  This alternate firmware request does not
permit chaining multiple packets in a single message, so each packet
results in a firmware request.  In addition, the different CPL message
requires more detailed information when enabling hardware checksums,
so parse_pkt() on VF devices must examine L2 and L3 headers for all
packets (not just TSO packets) for VF devices.  Finally, L2 checksums
on non-UDP/non-TCP packets do not work reliably (the firmware trashes
the IPv4 fragment field), so IPv4 checksums for such packets are
calculated in software.

Most of the other changes in the non-VF-specific code are to expose
various variables and functions private to the PF driver so that they
can be used by the VF driver.

Note that a limited subset of cxgbetool functions are supported on VF
devices including register dumps, scheduler classes, and clearing of
statistics.  In addition, TOE is not supported on VF devices, only for
the PF interfaces.

e06ab612d2 Don't break out of the m_advance() loop if len drops to zero.
If a packet contains the Ethernet header (14 bytes) in the first mbuf
and the payload (IP + UDP + data) in the second mbuf, then the attempt
to fetch the l3hdr will return a NULL pointer.  The first loop iteration
will drop len to zero and exit the loop without setting 'p'.  However,
the desired data is at the start of the second mbuf, so the correct
behavior is to loop around and let the conditional set 'p' to m_data of
the next mbuf (and leave offset as 0).
