Subject: [PATCH 2.6.21] iw_cxgb3 - Add set_tcb_rpl_handler.

Hey Roland,

This patch is needed for iw_cxgb3 to handle a change in the cxgb3 driver
posted by Divy that Jeff recently applied.  If the cxgb3 change is
destined for 2.6.21, then this change to iw_cxgb3 also needs to go in
(otherwise we get an error log entry for every rdma connection).  

It was an oversight that this patch didn't really get included in Divy's
series since the two go together.

See http://marc.info/?l=linux-netdev&m=117617444422260&w=2


Thanks,

Steve.

Add set_tcb_rpl_handler.

The Ethernet Driver no longer handles SET_TCB replies.
