Subject: ixp4xx_hss and netif_receive_skb

Hi...

I have modified Krzysztof Halasa's driver ixp4xx_hss to allow 4 HLDC
channels per HSS (if anyone is interested, I will post the changes,
but they are not ready for main stream yet).. I am able to transmit
and receive data using it.

The problem is that the received data is not sent to the listening
interface. I can see that netif_receive_skb returns a NET_RX_DROP, but
I loose myself in that point.

I am not sure of what is done in that function or if the desired
behaviour is the "deliver_skb", or the pt_prev->func.

Any clue in where to find some explanation about this function?

Thanks

Miguel Ángel Álvarez
