d308312acd tests/ncdevmem: Fix double-free of queue array 
[ Upstream commit 97c4e094a4 ]

netdev_bind_rx takes ownership of the queue array passed as parameter
and frees it, so a queue array buffer cannot be reused across multiple
netdev_bind_rx calls.

This commit fixes that by always passing in a newly created queue array
to all netdev_bind_rx calls in ncdevmem.

Fixes: 85585b4bc8 ("selftests: add ncdevmem, netcat for devmem TCP")

04db681f3c selftests: ncdevmem: Make client_ip optional 
[ Upstream commit 0ebd75f5f2 ]

Support 3-tuple filtering by making client_ip optional. When -c is
not passed, don't specify src-ip/src-port in the filter.

0738648a7d selftests: ncdevmem: Unify error handling 
[ Upstream commit bfccbaac1b ]

There is a bunch of places where error() calls look out of place.
Use the same error(1, errno, ...) pattern everywhere.

85585b4bc8 selftests: add ncdevmem, netcat for devmem TCP 
ncdevmem is a devmem TCP netcat. It works similarly to netcat, but it
sends and receives data using the devmem TCP APIs. It uses udmabuf as
the dmabuf provider. It is compatible with a regular netcat running on
a peer, or a ncdevmem running on a peer.

In addition to normal netcat support, ncdevmem has a validation mode,
where it sends a specific pattern and validates this pattern on the
receiver side to ensure data integrity.
