[PATCH] qla2xxx: add remote port codes...
Add initial support for FC remote port infrastructure. o Use fc_remote_port...() registration and block/unlock functions. o Consolidate 'attribute' (fc-remote/sysfs) helpers into new qla_attr.c file. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
