net-procfs: show net devices bound packet types
After commit:7866a621043f ("dev: add per net_device packet type chains"),
we can not get packet types that are bound to a specified net device by
/proc/net/ptype, this patch fix the regression.
Run "tcpdump -i ens192 udp -nns0" Before and after apply this patch:
Before:
[root@localhost ~]# cat /proc/net/ptype
Type Device Function
0800 ip_rcv
0806 arp_rcv
86dd ipv6_rcv
After:
[root@localhost ~]# cat /proc/net/ptype
Type Device Function
ALL ens192 tpacket_rcv
0800 ip_rcv
0806 arp_rcv
86dd ipv6_rcv
v1 -> v2:
- fix the regression rather than adding new /proc API as
suggested by Stephen Hemminger.
