FS#2169 - qca8337 switch does not support VLAN IDs > 128

Supply the following if possible:
- Device problem occurs on


- Software versions of OpenWrt/LEDE release, packages, etc.

openwrt 18.6.2 r7676-cddd7b4c77

- Steps to reproduce

attempt to configure a VLAN > 128

swconfig dev reports that it supports 128 VLANs with VLAN IDs in the range 0-4094
but with only 2 VLANs defined, you cannot set the vlan ID > 128

I do not find any option to enable larger VLAN IDs (enable4kvlans is not accepted)

Attribute 1 (int): vid (VLAN ID (0-4094))

This is wrong, as it's hardcoded value which doesn't reflect what is set in the code and should be probably fixed.

Anyway, to get it working, you probably need to increase value of `#define AR8X16_MAX_VLANS 128` in and recompile.
