[dpdk-dev] [PATCH v2] net/ice/base: fix wrong ptype bitmap for GRE

[Qi Zhang]

The ptype bitmap calculation for GRE packet is modified by misktake due to
commit: fc845a9d78ce ("net/ice/base: fix ptype mapping pollution from GTP flow")
which is target for GTP packet. The patch rollback that part of code.

Fixes: fc845a9d78ce ("net/ice/base: fix ptype mapping pollution from GTP flow")
