This Kconfig has wrongly been added to defconfig files. It is not the right place for it. It has never been the right place for it. Drivers that need it should select the symbol in their Kconfig entries. Drop PINCTL from Kconfig.defconfig and add proper select at Kconfig.sam*.

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.

|
|
Number of network buffers that will be permanently allocated by the
|
|
Ethernet driver. These buffers are used in receive path. They are
|
|
preallocated by the driver and made available to the GMAC module to be
|
|
filled in with incoming data. Their number has to be large enough to fit
|
|
at least one complete Ethernet frame. SAM ETH driver will always allocate
|
|
that amount of buffers for itself thus reducing the NET_BUF_RX_COUNT
|
|
which is a total amount of RX data buffers used by the whole networking
|
|
stack. One has to ensure that NET_PKT_RX_COUNT is large enough to
|
|
fit at least two Ethernet frames: one being received by the GMAC module
|
|
and the other being processed by the higher layer networking stack.
