Subject: p54: completely ignore rx'd frames with bad FCS
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=346de732cbd11bdc364ae80def2380a5002d7e6b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

p54: completely ignore rx'd frames with bad FCS

Passing frames with a bad FCS to the user is an optional feature.
However it doesn't work reliable and strangely not in the native monitor mode?!
