Trying to compile uImage with 8021Q enabled

Hi, I'm a newbie in compiling kernel images

I'm trying to compile the kernel for the NanoPi M3 with 8021Q enabled - but
I get the following error:
 "  CC      drivers/net/ethernet/nexell/nxpmac/nxpmac_main.o

Can anyone assist me perhaps?

Thanks

Generally it is telling you that some .h file has not been included in
nxpmac_main.c

List the #include .h files at the top of main

Search the whole directory for:
  NETIF_F_HW_VLAN_CTAG_RX

to try and find which .h file it is in.

The 2nd "error" is a warning.  The code should compile and work ... it is
just telling you to clean up the code.

Hi, 

Thanks for the response. Unfortunately I cannot find a .h file that
declares NETIF_F_HW_VLAN_CTAG_RX.

I have also searched the internet to no avail. Any further assistance would
be greatly appreciated.

I just noticed the word nexell.  

I suggest posting on the new forum.
