Minor cleanups to the devmem tcp code, and not-so-minor improvements to
the ksft.
For the cleanups:
- Address comment from Paolo post-merge.
- Fix whitespace.
- Add improvement dropped from Taehee's fix patch.
For the ksft:
- Add support for ipv4 environment.
- Add support for drivers that are li
This exit_wait seems necessary to make the rx side test pass for me.
I think this is just missed from the original test add patch. Add it now.

ncdevmem supports drivers that are limited to either 3-tuple or 5-tuple
FS support, but the ksft is currently 3-tuple only. Support drivers that
have 5-tuple FS supported by adding a ksft arg.

It's annoying for the list_add to be outside net_devmem_bind_dmabuf, but
the list_del is in net_devmem_unbind_dmabuf. Make it consistent by
having both the list_add/del be inside the net_devmem_[un]bind_dmabuf.

The current test just sends "hello\nworld" and verifies that is the
string received on the RX side. That is fine, but improve the test a bit
by sending 1K data. The test should be improved further to send more
data, but for now this should be a welcome improvement.
The test will send a repeating p
ncdevmem supports both ipv4 and ipv6, but the ksft is currently
ipv6-only. Propagate the ipv4 support to the ksft, so that folks that
are limited to these networks can also test.

As far as I can tell the ksft_disruptive here is unnecessary. These
tests are largerly independent, and when one test fails, it's nice to
know the results from all the other test cases.

The anon_inode_test test fails to build due to attempting to include
a nonexisting overlayfs/wrapper.h:
anon_inode_test.c:10:10: fatal error: overlayfs/wrappers.h: No such file or
directory

This is due to 0bd92b9fe53
The map_fixed_noreplace test does two blocks of test starting from a
mapping of 5 pages at the base address, logging a test result for each
initial mapping. These are logged with the same test name, causing test
automation software to see two reports for the same test in a single run.
