Subject: net: Add netdev interfaces for recording sends/comp
|
|
|
|
commit c5d67bd78c5dc540e3461c36fb3d389fbe0de4c3 upstream.
|
|
|
|
Add interfaces for drivers to call for recording number of packets and
|
|
bytes at send time and transmit completion. Also, added a function to
|
|
"reset" a queue. These will be used by Byte Queue Limits.
