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 if’s and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
