Apart from the 4-tuple (IP src/dst addresses and TCP/UDP src/dst port addresses), there are only 40-bits available to match other fields in packet headers. Not all combinations of packet header fields can fit in the 40-bit tuple. Currently, the combination of packet header fields to match are configured via filterMode for LETCAM filters and filterMask for HASH filters in firmware config files (t5/t6-config.txt). So, add devargs to allow User to dynamically select the filterMode and filterMask combination during runtime, without having to modify the firmware config files and reflashing them onto the adapter. A table of supported combinations is maintained by the driver to internally translate the User specified devargs combination to hardware's internal format before writing the requested combination to hardware Signed-off-by: Karra Satwik <kaara.satwik@chelsio.com> Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com>
