[PATCH net-next 1/2] selftests: drv-net: use env.rpath in the HDS test

[PATCH net-next 1/2] selftests: drv-net: use env.rpath in the HDS test

[Jakub Kicinski]

Commit 29b036be1b0b ("selftests: drv-net: test XDP, HDS auto and
the ioctl path") added a new test case in the net tree, now that
this code has made its way to net-next convert it to use the env.rpath()
helper instead of manually computing the relative path.

[PATCH net-next 2/2] selftests: net: use the dummy bpf from net/lib

[Jakub Kicinski]

Commit 29b036be1b0b ("selftests: drv-net: test XDP, HDS auto and
the ioctl path") added an sample XDP_PASS prog in net/lib, so
that we can reuse it in various sub-directories. Delete the old
sample and use the one from the lib in existing tests.
