[dpdk-dev] [PATCH v1] net/ice: fix burst Tx descriptor set issue

[Haiyue Wang]

The variables 'td_offset' and 'td_tag' should be reset to 0 for every
burst packet, otherwise the fields of Tx Descriptor will be set wrong,
this will cause the MDD event error, and Tx will hang.

Fixes: 17c7d0f9d6a4 ("net/ice: support basic Rx/Tx")
