[lvc-project] [PATCH 5.10 0/1] eth: ena: Check return value of xdp_convert_buff_to_frame

[Peter Kosyh]

Return value of a function 'xdp_convert_buff_to_frame' is dereferenced
without checking for null, but it is usually checked for this function.

This fixed in upstream commit <e8223eeff02> while refactoring. So,
simpler patch is offered for a stable version.
