From: Ilan Tayari <il...@mellanox.com>
Handler for ETHTOOL_GRXCLSRLALL must set info->data to the size
of the table, regardless of the amount of entries in it.
Existing code does not do that, and this breaks all usage of ethtool -N
or -n without explicit location, with this error:
rmgr: Invalid RX class rules table size: Success
Set info->data to the table size.
Tested:
ethtool -n ens8
ethtool -N ens8 flow-type ip4 src-ip 1.1.1.1 dst-ip 2.2.2.2 action 1
ethtool -N ens8 flow-type ip4 src-ip 1.1.1.1 dst-ip 2.2.2.2 action 1 loc 55
ethtool -n ens8
ethtool -N ens8 delete 1023
ethtool -N ens8 delete 55
Fixes: f913a72aa008 ("net/mlx5e: Add support to get ethtool flow rules")
