Subject: [PATCH 151/782] brcmfmac: Disable ARP offloading when promiscuous
|
|
|
|
This is a test patch for brcmfmac from Franky Lin at Broadcom to disable
|
|
ARP offloading when in promiscuous mode, re-enabling the ability to
|
|
sniff ARP packets over WiFi.
|
|
|
|
See: https://github.com/raspberrypi/linux/issues/2171
