Why not use more standard ether_ntoa ?

Because the rest of the code uses ll_addr_n2a. There is no user of
ether_ntoa in iproute2.

arpd is more of a standalone program.

I know but it is a part of the package (git tree). The other instances
use ll_addr_n2a. I'm ok with using ether_ntoa, I just wanted to follow
what is already there.

I can change it and post v2 it you want. I can also change other instances
of usage ll_addr_n2a to ether_ntoa.

Stephen, looks like you missed the last (3/3) patch from this set. I
can't see it in the iproute2 git.

Thanks

Oh, you already applied that before. That confused me because "iproute2:
ipa: show port id" actuall adds code which calls hexstring_n2a :)

Anyway, all good now. Sorry for the fuzz.
