From 8cdffdccd948ea4872b7b65280bc04f2fa93fc96 Mon Sep 17 00:00:00 2001 From: Yi Zou Date: Fri, 20 Nov 2009 14:54:57 -0800 Subject: [SCSI] libfcoe: add checking disable flag in FIP_FKA_ADV When the D bit is set if the FKA_ADV_Period of the FIP Discovery Advertisement, the ENode should not transmit period ENode FIP Keep Alive and VN_Port FIP Keep Alive (FC-BB-5 Rev2, 7.8.3.13). Note that fcf->flags is taken directly from the fip_header, I am claiming one bit for the purpose of the FIP_FKA_Period D bit as FIP_FL_FK_ADV_B, and use FIP_HEADER_FLAGS as bitmask for bits used in fip_header.
