Does the wired interface also have a method similar to WIFI TX burst mode and upload priority?
/etc/config/wirelss
WIFI CONFIG
option txburst '1'
No. Wired is point to point and full duplex, which means that there is no waiting for the channel to become open. On wireless the transmitter cannot be used until all the other stations in range have stopped transmitting.
I think that txburst is a g standard option and it is automatic on n and later.
