This selftest tests for cases where sendfile's 'count'
parameter is provided with a size greater than the intended
file size.
Motivation: When sendfile is provided with 'count' parameter
value that is greater than the size of the file, kTLS example
fails to send the file correctly. Last chunk of the file is
not sent, and the data integrity is compromised.
The reason is that the last chunk has MSG_MORE flag set
because of which it gets added to pending records, but is
not pushed.
Note that if user space were to send SSL_shutdown control
message, pending records would get flushed and the issue
would not happen. So a shutdown control message following
sendfile can mask the issue.

When running with conntrack rules, the dropped overlap fragments may cause
EPERM to be returned to sendto. Instead of completely failing, just ignore
those errors and continue. If this causes packets with overlap fragments to
be dropped as expected, that is okay. And if it causes packets that are
expected to be received to be dropped, which should not happen, it will be
detected as failure.

Using ping in tests is error-prone, because ping is too smart. On a
flaky system (notably in a simulator), when packets don't come quickly
enough, more pings are sent, and that throws off counters. Instead use
mausezahn to generate ICMP echo request packets. That allows us to
send them in quicker succession as well, because the reason the ping
was made slow in the first place was to make the tests work on
simulated systems.

Many systems build/test up-to-date kernels with older libcs, and
an older glibc (2.17) lacks the definition of SOL_DCCP in
/usr/include/bits/socket.h (it was added in the 4.6 timeframe).
Adding the definition to the test program avoids a compilation
failure that gets in the way of building tools/testing/selftests/net.
The test itself will work once the definition is added; either
skipping due to DCCP not being configured in the kernel under test
or passing, so there are no other more up-to-date glibc dependencies
here it seems beyond that missing definition.
