      Analysis
      BAD_POOL_CALLER : current irql=2 (DISPATCH_LEVEL), pooltype=1 (PagedPool) => we must use NonPagedPool instead of PagedPool for the allocation. Fix is probably to change PagedPool to NonPagedPool in sdk/lib/drivers/ip/network/receive.c:218

      It was aimed to be fixed by 0.4.15-dev-2793-g979b7d4
