Subject: [SCSI] qla2xxx: Fix virtual port failing to login after chip reset.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cefcaba67ab97fb756b3a6af5139c94d861b660d;p=linux-beck.git

[SCSI] qla2xxx: Fix virtual port failing to login after chip reset.

This patch ensures qla82xx_watchdog is not being run for the vport. It also
makes sure that beacon ON is not done for the vport, as it will lead to the
waking up of the dpc thread again and again.
