Hi,
While configuring ~500 multicast addrs, we ran into high order

This series enables a new work request to optimize small REG_MR
operations. This is intended for 4.9. If everyone agrees, I suggest
Doug take both the cxgb4 and iw_cxgb4 patches through his tree.
Thanks,
Steve.

Steve Wise (2):
cxgb4: advertise support for FR_NSMR_TPTE_WR
iw_cxgb4: add
Query firmware for the FW_PARAMS_PARAM_DEV_RI_FR_NSMR_TPTE_WR parameter.
If it exists and is 1, then advertise support for FR_NSMR_TPTE_WR to
the ULDs.

then use FW_RI_NSMR_TPTE_WR to pass down a fully populated TPTE for FW

Hi,
I have hit some weird (probably missing some detail) issue with drr.
Originally it was tested between two machines, then I quickly double
checked between namespaces (same behaviour) - the configuration follows:

ip li add name left type veth peer name ri

Setup_timer could be used instead of the cvall to init_timer and the

Change the default statistics ndo to return HW statistics
(like the one returned by ethtool_ops).
The HW stats are collected to a cache by delayed work every 1 sec.
Implement the offload stat ndo.
Add a function to get SW statistics, to be called from this function.

From: Nogah Frankel
Add a nested attribute of offload stats to if_stats_msg
named IFLA_STATS_LINK_OFFLOAD_XSTATS.
Under it, add SW stats, meaning stats only per packets that went via
slowpath to the cpu, named IFLA_OFFLOAD_XSTATS_CPU_HIT.

The problem we try to handle is about offloaded forwarded packets
which are not seen by kernel. Let me try to draw it:

Add a new ndo to return statistics for offloaded operation.
Since there can be many different offloaded operation with many
stats types, the ndo gets an attribute id by which it knows which
stats are wanted. The ndo also gets a void pointer to be cast according
to the attribut
Hi Dave,
And here's another set for net-next, it's been a month or so and we have a
reasonably large number of patches (for a change, mostly because I cleaned
up some WEP crypto thing and a few static checkers.)
Let me know if there's any problem.
Thanks,

Hi Dave,
Sorry - I know you only just pulled my tree for the previous fixes,
but we found two more problems in the last few days; it'd be great
to get those fixes in as well.
Let me know if there's any problem.

Write space becoming available may race with putting the task to sleep
