cnic: Defer iscsi connection cleanup The bnx2x devices require a 2 second quiet time before sending the last RAMROD command to destroy a connection. This sleep wait adds up to a long delay when iscsid is serially destroying maultiple connections. Create a workqueue to perform the final connection cleanup in the background to speed up the process. This significantly speeds up the process as the wait time can be done in parallel for multiple connections. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

cnic: Fix parity error code conflict The recently added parity error handling used an error code that was already defined for a different error. This could lead to bnx2x firmware assert. We need to fix this with new error codes that are defined for parity error only.
