net: ethernet: ti: am65-cpsw: add sw tx/rx irq coalescing based on hrtimers
Add SW IRQ coalescing based on hrtimers for TX and RX data path which
can be enabled by ethtool commands:
- RX coalescing
ethtool -C eth1 rx-usecs 50
- TX coalescing can be enabled per TX queue
- by default enables coalesing for TX0
ethtool -C eth1 tx-usecs 50
- configure TX0
ethtool -Q eth0 queue_mask 1 --coalesce tx-usecs 100
- configure TX1
ethtool -Q eth0 queue_mask 2 --coalesce tx-usecs 100
- configure TX0 and TX1
ethtool -Q eth0 queue_mask 3 --coalesce tx-usecs 100 --coalesce tx-usecs 100
show configuration for TX0 and TX1:
ethtool -Q eth0 queue_mask 3 --show-coalesce
Comparing to gro_flush_timeout and napi_defer_hard_irqs, this patch
allows to enable IRQ coalesing for RX path separately.
