A probable bug in nftables doc

A probable bug in nftables doc

[Eve Adam]

Hello,

It seems that section 'ICMPV6 TYPE TYPE' and 'ICMPVX CODE TYPE' of
nftables doc have some problems:

The keyword of 'icmpv6 type type' probably should be 'icmpv6_type'
rather than 'icmpx_code';
meanwhile, the keyword of 'icmpvx code type' probably should be
'icmpx_code' rather than 'icmpv6_type'.

This issue can also be verified by typing the command 'nft describe
icmpv6_type' and 'nft describe icmpx_code' and comparing their actual
output with the output described by the doc.

I found the issue in 'nftables v0.9.8 (E.D.S.)'. But it is also the
case in the newest version v1.0.4.
