[PATCH v4 net 0/4] net: enetc: fix some issues of XDP

Posted by Wei Fang 1 month, 2 weeks ago

We found some bugs when testing the XDP function of enetc driver,
and these bugs are easy to reproduce. This is not only causes XDP
to not work, but also the network cannot be restored after exiting
the XDP program. So the patch set is mainly to fix these bugs. For
details, please see the commit message of each patch.
