Subject: [PATCH] bcmgenet: Better coalescing parameter defaults
|
|
|
|
|
|
|
|
|
|
Set defaults for TX and RX packet coalescing to be equivalent to:
|
|
|
|
|
|
|
|
|
|
# ethtool -C eth0 tx-frames 10
|
|
|
|
|
# ethtool -C eth0 rx-usecs 50
|
|
|
|
|
|
|
|
|
|
This may be something we want to set via DT parameters in the
|
|
|
|
|
future.
