Maybe you can wrote: In FM10K, a single PF device can derive out a few logical ports, like SRIOV VF device, VMDQ object. To better manage them, FM10K silicon assigned a Unique GLORT ID to each logical ports. When a logical port sends a broadcast packet, the silicon will flood it to all Logical ports, including the one sent the broadcast packet. To prevent this, silicon has a rxq register to fill the glort id of the logical port that queue binds to.... > Signed-off-by: Shaopeng He <shaopeng.he at intel.com> > --- > drivers/net/fm10k/fm10k_ethdev.c | 18 +++++++++++++++++- > 1 file changed, 17 insertions(+), 1 deletion(-) > > diff --git a/drivers/net/fm10k/fm10k_ethdev.c > b/drivers/net/fm10k/fm10k_ethdev.c > index f6eb05d..60f821a 100644 > --- a/drivers/net/fm10k/fm10k_ethdev.c > +++ b/drivers/net/fm10k/fm10k_ethdev.c > @@ -690,12 +690,15 @@ static int > fm10k_dev_rx_init(struct rte_eth_dev *dev)
