Subject: [PATCH iproute2-next v2 3/5] iprule: Allow specifying ports in hexadecimal notation

This will be useful when enabling port masks in the next patch.

Before:

 # ip rule add sport 0x1 table 100
 Invalid "sport"

After:

 # ip rule add sport 0x1 table 100
 $ ip rule show sport 0x1
 32765:  from all sport 1 lookup 100
