Ethernet ports now need to register to the multicast groups, we can not longer
use the default multicast queue per port because of the multiple "clients" per
port.

Each slave gets one msi-X for completions, the master also gets one for

Affiliated and unaffiliated asynch events are handled by a single EQ owned by
the master. A per-slave SW event queue is added to log and dispatch both
slave-specific
events and events that apply to all slaves.

Hello Roland,
This is another round of SRIOV support patches for mlx4.
Currently the support is for the mlx4_core and mlx4_en modules.
The main changes from previous round are:
1. Events on the Communication channel, no more polling.
2. Steering mechanism change for Ethernet traffic.
Thanks,
Yevge
Hello Roland,
We plan to submit SRIOV support patches this week for the low level and
Ethernet drivers.
This code should not contradict with the RoCEE patches submitted by Eli
(patches generating against tree without RoCEE would fail on a tree with
RoCee). So which tree should we generate the pa
Instead always setting all the TX cqs to use comletion vector 0,
let the mlx4_core to distribute them to avoid situation where some eqs
are very loaded while other do nothing.
