IB/srp: Maintain a single connection per I_T nexus
Quoted 10 lines
An SRP target is required to maintain a single connection between initiator and target. This means that if the '
add_target' attribute is used to create a second connection to a target that the first connection will be logged out and that the SCSI error handler will kick in. The SCSI error handler will cause the SRP initiator to reconnect, which will cause I/O over the second connection to fail. Avoid such ping-pong behavior by disabling relogins. Note: if reconnecting manually is necessary, that is possible by deleting and recreating an rport via sysfs.

This patch differs slightly from what Sebastian had posted. But if Sebastian agrees with this version, I'll be happy to add his signed-off-by.
Bart.
