Mesh not supported

[elockman]

I am building a linux image with yocto for the SAMA5D2-XULT board.
I am trying to assign mesh type to an RT5370 USB wifi device.
This worked in the past, but mesh is no longer supported for some reason.

root@sama5d2-xplained:~# iw wlan0 interface add mesh0 type mp mesh_id mymesh
**command failed: Operation not supported (-95)**

iw list yields:

        Supported interface modes:
                 * IBSS
                 * managed
                 * AP
                 * AP/VLAN
                 * monitor

I suspect my mesh config is not being applied properly with the new Linux-mchp version.

I am building with linux-mchp_5.10.80

my linux-mchp_5.10.80.bbappend file includes:

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI_append = " file://xult_dts.patch;patch=1"
SRC_URI_append += " file://defconfig.patch"

and the defconfig patch includes:

diff --git a/arch/arm/configs/at91_dt_defconfig b/arch/arm/configs/at91_dt_defconfig

The image builds, but the mesh configuration does not seem to stick.

Additional info:
I am using RT5370 USB WiFi module with rt2800usb driver.

Unplugging and plugging in the module, shows that Linux is recognizing the module

I've also removed it with rmmod and reinstalled with modprobe
rmmod rt2800usb
modprobe rt2800usb nohwcrypt=0

lsmod shows the driver is installed.
