Hi All,
This patch series provides miscelleneous fixes for Chelsio T4/T5 adapters
related to cxgb4 related to sge and mtu. And includes DB Drop avoidance
and other misc. fixes on iw-cxgb4.
The patches series is created against David Miller's 'net-next' tree.
And includes patches on cxgb4 and

Commit 0034b29 (cxgb4: Don't assume LSO only uses SGL path in t4_eth_xmit())
introduced a regression where-in length was calculated wrongly for LSO path,
causing chip hangs.
So, correct the calculation of len.

Currently ring_tx_db() can deadlock if a db_full interrupt fires and is
run on the same while ring_tx_db() has the db lock held. It needs to
disable interrupts since it serializes with an interrupt handler.

We cannot save the mapped length using the rdma max_page_list_len field
of the ib_fast_reg_page_list struct because the core code uses it. This

The debugfs init code was incorrectly called before

Mike Marciniszyn (2):
IB/qib: Add percpu counter replacing qib_devdata
This patch replaces the dd-int_counter with a percpu counter.
The maintanance of qib_stats.sps_ints and int_counter are
combined into the new counter.
There are two new functions added to read the counter:
- qib_int_counter (for a particular qib_devdata)
- qib_sps_ints (for all HCAs)
A
The counters, unicast_xmit, unicast_rcv, multicast_xmit, multicast_rcv
are now maintained as percpu variables.
The mad code is modified to add a z_ latch so that the percpu counters
monotonically increase with appropriate adjustments in the reset,
read logic to maintain the z_ latch.
This patch
Resurrecting an old issue :)

Sure, no problem.
Do you have a git tree with the latest versions of all the changes you
want for 3.15 in a branch? That would be helpful as I catch up on
applying things, so that I don't miss anything.
If you don't have one, taking a little time to set one up on github or
wherever would be
So I went ahead and applied this for 3.15, although I suspect the
verbs API is probably the wrong one. I understand that the mlx5
microarchitecture requires some of this signature binding stuff to go
through a work queue, but conceptually I don't think the
