[dpdk-dev] [PATCH] net/hns3: fix IEEE 1588 PTP

[dpdk-dev] [PATCH] net/hns3: fix IEEE 1588 PTP

[Min Hu (Connor)]

When jumbo frame is enabled, Rx function will choose 'Scalar Scattered'
function which has no PTP handling.

This patche fixed it by add PTP handling in 'Scalar Scattered' function.

Fixes: 38b539d96eb6 ("net/hns3: support IEEE 1588 PTP")
