Herbert Xu's commit fb93134dfc, entitled
"[TCP]: Fix size calculation in sk_stream_alloc_pskb", has triggered a
bug in the 5701 where the 5701 DMA engine will corrupt outgoing
packets. This problem only happens when the starting address of the
packet matches a certain range of offsets and only when the 5701 is
placed downstream of a particular Intel bridge.
This patch detects the problematic bridge and if present, readjusts the
starting address of the packet data to a dword aligned boundary.
