CONFIG_ETH_SAM_GMAC_FORCE_QUEUE

Force all traffic to be routed through a specific queue

Type: bool

Help

This option is meant to be used only for debugging. Use it to force all
traffic to be routed through a specific hardware queue. With this enabled
it is easier to verify whether the chosen hardware queue actually works.
This works only if there are four or fewer RX traffic classes enabled, as
the SAM GMAC hardware supports screening up to four traffic classes.

Direct dependencies

ETH_SAM_GMAC_QUEUES > 1 && NET_TC_RX_COUNT < 5 && ETH_SAM_GMAC && NET_L2_ETHERNET

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
