Alexander Lobakin says:
Now that ice uses libeth for managing Rx buffers and supports
configurable header split, it's ready to get support for sending
and receiving packets with unreadable (to the kernel) frags.
Extend libeth just a little bit to allow creating PPs with custom
memory providers and make sure ice works correctly with the netdev
ops locking. Then add the full set of queue_mgmt_ops and don't
unmap unreadable frags on Tx completion.
No perf regressions for the regular flows and no code duplication
implied.
Credits to the fbnic developers, which's code helped me understand
the memory providers and queue_mgmt_ops logics and served as
a reference.
