Re: [PATCH 4/6 v2] IB: address translation to map IP toIB addresses (GIDs)

[Roland Dreier <rdreier@cisco.com>]

The ib_addr module depends on CONFIG_INET, because it uses symbols
like arp_tbl, which are only exported if INET is enabled.

I fixed this up by creating a new (non-user-visible) config symbol to
control when ib_addr is built -- I put the following diff on top of
your patch in my tree:
