Default Programmable Buffer Length in rk3399's gmac is not suitable
|
|
for MTUs higher than 1498. The easiest solution would be to disable
|
|
offloading but it is not ideal as it disables hardware checksumming.
|
|
|
|
This patch sets pbl to 0x4 which is good for the most popular MTU
|
|
value of 1500.
