[dpdk-dev] [PATCH v4 0/3] support flow for IP fragment in ICE

[Jeff Guo]

Support RSS hash and FDIR for IP fragment packets in ICE PMD.

v4:
correct typo when define fragment
v3:
rebase code and fix some parsing issues.
v2:
add some input check

Jeff Guo (3):
  net/ice/base: support IP fragment RSS and FDIR
  net/ice: support RSS hash for IP fragment
  net/ice: support FDIR for IP fragment packet

Support RSS hash and FDIR for IP fragment packets in ICE PMD.

v4:
correct typo when define fragment
v3:
rebase code and fix some parsing issues.
v2:
add some input check

[dpdk-dev] [PATCH v6 0/3] support flow for IP fragment in ICE

[Jeff Guo]

Support RSS hash and FDIR for IP fragment packets in ICE PMD.

v6:
fix uninitialize issue
v5:
rebase code.
v4:
correct typo when define fragment
v3:
rebase code and fix some parsing issues.
v2:
add some input check
