The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Fix this by returning 'netdev_tx_t' in this driver too.

Maybe inside ks_wlan_start_xmit, instead of "return 0;", there should be 
"return NETDEV_TX_OK;" and "return NETDEV_TX_BUSY;" otherwise. It is 
just suggestion.

Maybe inside ks_wlan_start_xmit, instead of "return 0;", there should be 
"return NETDEV_TX_OK;" and "return NETDEV_TX_BUSY;" otherwise. It is 
just suggestion.

I see, yes. However, since:
1) this sort of change is really outside the goal of this patch;
2) more change are needed for returning NETDEV_TX_BUSY (most not
   free the skb, probably should stop the queue/device, ...);
3) the driver is actively improving by someone just now (Sergio);
I prefer to let this change to Sergio.

I'll resend my (unimportant) change in a few weeks (if still needed).


Cheers,

Fix this by returning 'netdev_tx_t' in this driver too and
