Subject: scsi: be2iscsi: Reinit SGL handle, CID tables after TPE
X-Git-Tag: v4.11-rc1~141^2~156
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd940972f36779577701f20965847e9b56b79a0e;p=karo-tx-linux.git

scsi: be2iscsi: Reinit SGL handle, CID tables after TPE

After TPE recovery, CID table needs to be repopulated as per CIDs in
WRBQ creation responses.

SGL handles table needs to be recreated for posting and its indices need
to be resetted.

This is achieved by calling beiscsi_cleanup_port when disabling and
beiscsi_init_port in enabling port.
