This results in a kernel crash if the arp does indeed time out.

This bug wasn't detectable until newer FW that moves connections out of RDMA mode as soon as an error is detected. QP can exit RTS before the last AE arrives. This was introduced by changes in the FW to kick connections out of RDMA mode as soon as an error is detected. A side effect of this is that the driver can move the QP out of RTS before the AE causing the connection to get kicked out of RDMA mode is processed. Fix for this is to always post async errors even if the QP is out of RTS.

Use LLD api cxgb4_create_server and cxgb4_create_server6 for initiating passive open connections. Similarly use cxgb4_remove_server to remove the passive open connections in place of listen_stop. Add support for iWARP over VLAN device and enable IPv6 support on VLAN device. Make use of import_ep in c4iw_reconnect.

Change the references of local_addr and remote_addr in cxgb4, cxgb3, nes and amso drivers to match this. However to be able to actully run traffic over IPv6, low-level drivers have to add code to support this.

Further, TCPCT does not fully implement RFC 6013. As a nice side-effect, removing TCPCT increases TCP's performance for very short flows: Doing an apache-benchmark with -c 100 -n 100000, sending HTTP-requests for files of 1KB size. before this patch: average (among 7 runs) of 20845.5 Requests/Second after: average (among 7 runs) of 21403.6 Requests/Second Signed-off-by: Christoph Paasch <christoph.paasch@uclouvain.be> Signed-off-by: David S.
