[SCSI] libfc: add FC-BB-5 LESB counters to fcoe_dev_stats
Yi Zou [Fri, 20 Nov 2009 22:54:52 +0000 (14:54 -0800)]
FC-BB-5 Rev2.0, Clause 7.10 extends the FC-LS-3 LESB for FC-BB_E. We are
already tracking Link Failure Count so add the rest in this patch.

For VLinkFailureCount and MissDiscAdvCount, they are part of the per-cpu
fcoe_dev_stats. For SymbolErrorCount, ErroredBlockCount, and FCSErrorCount,
they are defined in IEEE 802.3-2008 and are per LLD. They are expected to
come from LLD.
