Subject: qed: Fix non TCP packets should be dropped on iWARP ll2 connection

From: Michal Kalderon <[email protected]>

[ Upstream commit 16da09047d3fb991dc48af41f6d255fd578e8ca2 ]

FW workaround. The iWARP LL2 connection did not expect TCP packets to arrive on it's connection. The fix drops any non-tcp packets

Fixes b5c29ca ("qed: iWARP CM - setup a ll2 connection for handling SYN packets")
