Hi all:
in struct net_device
there is a function pointer rx_handler_func_t __rcu *rx_handler
it's very convenient to register a function in an externel module
and do some special handlings
so i think what about to add an tx_handler_func
before ndo_start_xmit() been invoked
and do some special things before transmit
is it necessary or there is already some other better methods to achieve this goal ?
Thank you all

Jiri:
1. do some filter rules implemented in an externl module
without NF_HOOK on a bridge
2. output skb through NIC and virtual net_devices
3. mirror a port
and so on.
