    Is this a fix of the previous patches? looks strange to just start
    advertising a feature bit but not add any code..

The previous related commits were merged already:
0af3c4e2eab8 net: ena: changes to RSS hash key allocation
c1bd17e51c71 net: ena: change default RSS hash function to Toeplitz
f66c2ea3b18a net: ena: allow setting the hash function without changing the key
e9a1de378dd4 net: ena: fix error returning in ena_com_get_hash_function()
80f8443fcdaa net: ena: avoid unnecessary admin command when RSS function set fails
6a4f7dc82d1e net: ena: rss: do not allocate key when not supported
0d1c3de7b8c7 net: ena: fix incorrect default RSS key

This commit was not included by mistake, so we are adding it now.
