Subject[PATCH AUTOSEL 5.4 16/26] nvmet-fc: do not check for invalid target port in nvmet_fc_handle_fcp_rqst()
Date
From: Hannes Reinecke <hare@suse.de>

[ Upstream commit 2a4a910aa4f0acc428dc8d10227c42e14ed21d10 ]

When parsing a request in nvmet_fc_handle_fcp_rqst() we should not
check for invalid target ports; if we do the command is aborted
from the fcp layer, causing the host to assume a transport error.
Rather we should still forward this request to the nvmet layer, which
will then correctly fail the command with an appropriate error status.
