[dpdk-dev] [PATCH] net/ixgbe: fix possible uninitialized variable

[Haiyang Tan <haiyangtan@tencent.com>]

The uninitialized field 'extra_flag' of hash parameter may enable
certain feature silently. Typically, if bit0 of 'extra_flag' set, the
hardware transactional memory support will be enabled unexpectedly.
