[dpdk-dev] [PATCH 2/2] app/testpmd: retain original FDIR mode when configuring DCB

["Wei Hu (Xavier)" <huwei013@chinasoftinc.com>]

From: Huisong Li <lihuisong@huawei.com>

Sometimes, we have to start testpmd application with --pkt-filter-mode to
test flow table feature. When using 'port config 0 dcb vt off 4 pfc on'
command, the dcb information are configured in init_port_dcb_config
function by get_eth_dcb_conf function, And then rte_eth_dev_configure API
function will be called to re-configure PMD driver.

The values of rxmode and txmode in rte_eth_conf struct used to configure
PMD driver, come from the current values maintained in testpmd. However,
the fdir_conf.mode in rte_eth_conf struct is not set, which may cause that
some PMD driver cannot test the flow table feature when multiple TCs are
enabled.
