Subject: [PATCH] net: af_packet: fix procfs header for 64-bit pointers
On 64-bit systems the packet procfs header field names following 'sk'
are not aligned correctly:
sk RefCnt Type Proto Iface R Rmem User Inode
00000000605d2c64 3 3 0003 7 1 450880 0 16643
00000000080e9b80 2 2 0000 0 0 0 0 17404
00000000b23b8a00 2 2 0000 0 0 0 0 17421
...
With this change field names are correctly aligned:
sk RefCnt Type Proto Iface R Rmem User Inode
000000005c3b1d97 3 3 0003 7 1 21568 0 16178
000000007be55bb7 3 3 fbce 8 1 0 0 16250
00000000be62127d 3 3 fbcd 8 1 0 0 16254
...
