By default, the network interfaces use a pool channel, see
dpaa_get_channel() in dpaa_eth_priv_probe(). To enable a dedicated QMan
software portal, use libbsd,dedicated-portal = "enabled";. This option
is useful for special purpose 10Gbit/s Ethernet processing.
/ {
soc: soc@ffe000000 {
fman0: fman@400000 {
enet7: ethernet@f2000 {
libbsd,dedicated-portal = "enabled";
};
};
};
};
The dequeue support for processor affine QMan portals may be explicitly
disabled. The dequeue support is responsible for receiving frames and
completion of frame transmission, e.g. buffer recycling. Without at
least one enabled dequeue support, there will be no networking.
/ {
qman-portals@ff6000000 {
qman-portal@0 {
libbsd,dequeue = "disabled";
};
};
};
