[PATCH v2 4/6] qla2xxx: Send FC4 type NVMe to the management server
Madhani, Himanshu
himanshu.madhani at cavium.com
Wed Jun 21 13:48:44 PDT 2017
From: Duane Grigsby <duane.grigsby at cavium.com>
This patch adds switch command support for FC-4 type of FC-NVMe (0x28)
for resgistering HBA port to the management server. RFT_ID command is
used to register FC-4 type of 0x28 and RFF_ID is used to register
FC-4 features bits for FC-NVMe port.
