[B.A.T.M.A.N.] pull request [net]: batman-adv 20150616

[Antonio Quartulli <antonio@meshcoding.com>]

Hello David,

this is a pull request intended for net/linux-4.1.
I know it is rather late in the release cycle, but the fixes are
pretty small and they were worth being sent now.

Patch 1/2 fixes an overflow of a u32 variable that may happen while
computing the metric to select the best batman-GW in the network.
** It would be great if this patch could be queued for inclusion in
any stable release >= 3.2


Patch 2/2 prevents the Distributed ARP Table from forging unwanted
ARP replies on behalf of another host that may fool an Ethernet switch
sitting behind batman-adv.
** It would be great if this patch could be queued for inclusion in
any stable release >= 3.8


Please pull or let me know if something is wrong

Thanks a lot,
	Antonio
