Early ISP2432 parts have a known hardware issue when coming out of a D3 hot state. This issue can result in a hung PCIe link. Recent firmwares contain a workaround whereby the stop-firmware mailbox command prevents the ISP from entering the D3 hot state. In order to ensure that the workaround succeeded the driver must verify that the stop-firmware mailbox command completes successfully. In the event of a failure, the driver attempts a shutdown-retry after resetting the ISP and re-executing firmware.

We could hack around netlink's lack of mempool support like dm, but it is just too ulgy (dm's hack is ugly enough :) when you need to support broadcast. This patch removes the recv pools. We have not used them even when we were allocting 20 MB per session and the system only had 64 MBs. And we have no pools on the send side and have been ok there. When Peter's work gets merged we can use that since the network guys are in favor of that approach and are not going to add mempools everywhere.

Just notifying SCSI-ML and retry is not enough as we have to make sure the SCSI bus is not getting confused, either. So whenever we detect an external reset we rewrite the command to TUR, disable packetized command and notify the internal engine that an abort has happened. This way we trigger a proper bus reset sequence and all devices will be renegotiated properly. Kudos to Justin Gibbs and Luben Tuikov for this idea.

Some ATAPI devices choke when shorter CDB is used and the left bytes contain garbage. Block SG_IO cleared left bytes but SCSI SG_IO didn't. This patch makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO.
