Subject: [SCSI] libfcoe: Send port LKA every FIP_VN_KA_PERIOD secs.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f47dd855d9e64a5d499a93e858a82bc5e7b21345;p=openwrt%2Fstaging%2Fblogic.git

[SCSI] libfcoe: Send port LKA every FIP_VN_KA_PERIOD secs.

libfcoe module doesnt send port keep alive every
FIP_VN_KA_PERIOD due to improper assignment of timeout value.
Update the port_ka_time appropriately by incrementing it by
FIP_VN_KA_PERIOD in fcoe_ctlr_timeout(), so that the link_work
is scheduled to send the port LKA.
