net/mlx5e: Use flow keys dissector to parse packets for ARFS
[ Upstream commit 405b93eb764367a670e729da18e54dc42db32620 ]
The current ARFS code relies on certain fields to be set in the SKB
(e.g. transport_header) and extracts IP addresses and ports by custom
code that parses the packet. The necessary SKB fields, however, are not
always set at that point, which leads to an out-of-bounds access. Use
skb_flow_dissect_flow_keys() to get the necessary information reliably,
fix the out-of-bounds access and reuse the code.
