Subject: [PATCH 3/3] rndis_host: limit scope of bogus MAC address detection to
|
|
ZTE devices
|
|
MIME-Version: 1.0
|

Content-Type: text/plain; charset=UTF-8

|
|
|
|
Reporting of bogus MAC addresses and ignoring configuration of new
|
|
destination address wasn't observed outside of a range of ZTE devices,
|
|
among which this seems to be the common bug. Align rndis_host driver
|
|
with implementation found in cdc_ether, which also limits this workaround
|
|
to ZTE devices.
