- not touched: wifi patches, those still require work before rebase is consistent.
- `wifi-4003-uwe5622-adjust-for-rockchip.patch`
- this patch is done on top of the wifi drivers patches exclusively, and fails to apply out of tree.
- we should probably consider moving this into the wifi drivers patch harness, not in the rockchip tree.

Subject: Disable MTU validation
|
|
|
|
This patch reverts: https://github.com/torvalds/linux/commit/eaf4fac478077d4ed57cbca2c044c4b58a96bd98
|
|
|
|
It works around following issues:
|
|
- no way to change MTU (tx_fifo_size is reported as 0 for Rockchip's dwmac)
