Subject: re: team: add broadcast mode

Hello Jiri Pirko,

The patch 5fc889911a99: "team: add broadcast mode" from Jul 11, 2012, 
leads to the following Smatch warning:
drivers/net/team/team_mode_broadcast.c:46 bc_transmit()
	 warn: signedness bug returning '18446744073709551516'

The error message sucks because 18446744073709551516 is -100 as an int,
and I'm not sure how it figures this returns -100...

But actually there is a signedness bug in bc_transmit().  We return
error codes from team_dev_queue_xmit() and cast them to 1 as bool.  This
function is supposed to return 1 on success but instead it returns zero.

regards,
dan carpenter
