[dpdk-dev] [PATCH 03/20] net/ena: add reset reason in rx error

[Michal Krawczyk]

From: Rafal Kozik <rk at semihalf.com>

Whenever the driver will receive too many descriptors from the device,
it should trigger the device reset with reset reason set to
ENA_REGS_RESET_TOO_MANY_RX_DESCS.

Fixes: 241da076b1f7 ("net/ena: adjust error checking and cleaning")
