[dpdk-dev] [PATCH] net/i40e/vf: reset scatter_rx flag when configuration complies

[eduser25@gmail.com]

From: Eduard Serra <eduser25@gmail.com>

Scatter RX (scattered_rx) flag is currently not being resetted
when new configuration is suplied to reconfigure a port,
rendering the rx callback logic to always fall through the
scatter branch.
