[][kernel][mt7988][eth][Add DIP dynamic allocation to the LRO]
[Description]
Add DIP dynamic allocation to the LRO.
The LRO2 is equipped with only 4 DIP registers, with each GMAC occupying
2 DIPS. As a result, GMAC3 will not be able to allocate a DIP register.
Therefore, we add a dymanic allocation to enhance the user scenario.
Besides, users can utilize the commands listed below to operate LRO.
- Check LRO status
ethtool -k ethX |grep large-receive-offload
- Turn on LRO
ethtool -K ethX lro on
// Please ensure that ethX has been remove from br-lan
- Turn off LRO
ethtool -K ethX lro off
// Please ensure that ethX has been remove from br-lan
- Add LRO RX action
ethtool -N ethX flow-type tcp4 dst-ip DIP action 0 loc Y
// DIP can be any arbitrary IP address, and Y can be 0 or 1
- Dump LRO RX action
ethtool -n ethX
Without this patch, GMAC3 will not be able to allocate a DIP register.
