Subject: [SCSI] libfcoe: don't send ELS in FIP mode if no FCF selected
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f31f2a1c3215e96fbff2152486d0fb590f72634e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] libfcoe: don't send ELS in FIP mode if no FCF selected

If link is up, but no FCF is selected, don't send any ELS frames.

This came up when an fnic received a multicast advertisement but
no solitited advertisments, so no FCF was selected.  It tried
to send FLOGIs anyway.
