nrf52/ieee802.15.4/6lowpan server crash

[maxikrie]

Hello,

I have done some testing with more heavy duty sending (100 Hz). The server occasionally crashes in the hpwork queue thread. I have increased stack size of the thread with no noticeable improvements.

I am testing with two nrf52840-dk boards.

Tagging @raiden00pl since you provided the original work.

Thanks!

This is probably a problem with the ieee802154 stack in NuttX because I observed similar crashes with mrf24j40 (connected to nrf52).
