netfilter: nft_meta: deal with PACKET_LOOPBACK in netdev family
After adding the following nft rule, then ping 224.0.0.1: # nft add rule netdev t c pkttype host counter The warning complain message will be printed out again and again: WARNING: CPU: 0 PID: 10182 at net/netfilter/nft_meta.c:163 \ nft_meta_get_eval+0x3fe/0x460 [nft_meta] [...] Call Trace: <IRQ> dump_stack+0x85/0xc2 __warn+0xcb/0xf0 warn_slowpath_null+0x1d/0x20 nft_meta_get_eval+0x3fe/0x460 [nft_meta] nft_do_chain+0xff/0x5e0 [nf_tables] So we should deal with PACKET_LOOPBACK in netdev family too. For ipv4, convert it to PACKET_BROADCAST/MULTICAST according to the destination address's type; For ipv6, convert it to PACKET_MULTICAST directly.
