+   Previous NICs support matching on either IPv6 src or dst in a rule.
+   In general, the matching limitation is related to the number of DWORDS:
+   older hardware supports up to 5 DWORDS for matching,
+   while newer hardware (ConnectX-8/BlueField-3 and up)
+   supports up to 11 DWORDS for matching.
