Subject: [PATCH 04/12] mediatek: fix packet corruption on bridged interface
|
|
|
|
This fixes problem that was reported here:
|
|
http://forum.banana-pi.org/t/openwrt-18-06-malformed-ip-packets-at-bridged-interface/
|
|
|
|
Fix is to set both gmacs to use trgmii mode.
|
|
This fix is not technically correct as second gmac
|
|
does not support trgmii mode but current driver
|
|
implementation seems to handle it somehow and
|
|
it is the only way to have both gmacs enabled
|
|
and avoid corruption of the packets on brigded
|
|
lanX interfaces.
|
