Pable Neira Ayuso says:
====================
The following patchset contains Netfilter fixes for net:
1) Increase timeout to 120 seconds for netfilter selftests to fix
nftables transaction tests, from Florian Westphal.
2) Fix overflow in bitmap_ip_create() due to integer arithmetics
in a 64-bit bitmask, from Gavrilov Ilia.
3) Fix incorrect arithmetics in nft_payload with double-tagged
vlan matching.
