[PATCH 18/26] lpfc: Register for Application Services FC-4 type in Fabric topology

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add new FC-4 type 0x60 Application Services for fabric registration when
VMID is enabled.

Modified rft struture to indicate __be format. Removed redundant ipReg
variable as it was not used.
