Subject: [PATCH 3/5] ib_srpt: depend on INFINIBAND_ADDR_TRANS

INFINIBAND_SRPT code depends on INFINIBAND_ADDR_TRANS provided symbols.
So declare the kconfig dependency. This is necessary to allow for
enabling INFINIBAND without INFINIBAND_ADDR_TRANS.

Isn't INFINIBAND && INFINIBAND_ADDR_TRANS a bit redundant? Can't have
INFINIBAND_ADDR_TRANS without INFINIBAND.

By kconfig INFINIBAND_ADDR_TRANS depends on INFINIBAND. So yes, it seems
redundant. I don't know if anyone has designs to break this dependency and
allow for ADDR_TRANS without INFINIBAND. Assuming not, I'd be willing to
amend my series removing redundant INFINIBAND and a followup series to
remove it from similar depends. Though I'm not familiar with rdma dev tree
lifecycle. Is rdma/for-rc a throw away branch (akin to linux-next), or
will it be merged into linus/master? If throwaway, then we can amend
its patches, otherwise followups will be needed.

Let me know what you'd prefer. Thanks.

FYI from v4.17-rc3:
drivers/staging/lustre/lnet/Kconfig: depends on LNET && PCI && INFINIBAND
&& INFINIBAND_ADDR_TRANS
net/9p/Kconfig: depends on INET && INFINIBAND && INFINIBAND_ADDR_TRANS
net/rds/Kconfig: depends on RDS && INFINIBAND && INFINIBAND_ADDR_TRANS
net/sunrpc/Kconfig: depends on SUNRPC && INFINIBAND &&
INFINIBAND_ADDR_TRANS

No, not at the moment (and I'm not sure we ever would, it would only
happen if the subsystem itself became something like RDMA and INFINIBAND
specifically related only to the INFINIBAND link layer support, in which
case you might want to enable RoCE without INFINIBAND or something like
that, but no one has plans to do that as far as I'm aware).

Followups will be needed.

I think a single update patch to fix all of these, and the
pre-existing ones would be great
