Vlad,
Please pull these Chelsio cxgb3 and iw_cxgb3 fixes from
git://git.openfabrics.org/~swise/ofed_1_2 ofed_1_2
Short log
---------
Divy Le Ray:
Fix a deadlock when the interface s configured down and
The MAC watchdog was failing if the peer interface was brought down.
Remove specific CPL handler.
Steve Wise:
Initialize cpu_idx field in cpl_close_listserv_req message.
Backport rtnl_trylock() for Chelsio Driver.
Add set_tcb_rpl_handler.
