Subject: ethdev: validate offloads set by PMD
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1daa33805824e2fb6c93723604750d7b4013a355;hp=1daa33805824e2fb6c93723604750d7b4013a355;p=dpdk.git

ethdev: validate offloads set by PMD

Some PMDs cannot work when certain offloads are enable/disabled, as a
workaround PMDs auto enable/disable offloads internally and expose it
through dev->data->dev_conf.rxmode.offloads.

After device specific dev_configure is called compare the requested
offloads to the offloads exposed by the PMD and, if the PMD failed
to enable a given offload then log it and return -EINVAL from
rte_eth_dev_configure, else if the PMD failed to disable a given offload
log and continue with rte_eth_dev_configure.
