Summary - tl-wr740n-v4 with wrong switch port order on LuCI 
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Here's the port layout:

# in case     # in swconfig    # in LuCI    # desired
1             2                LAN3         LAN1
2             3                LAN2         LAN2
3             4                LAN1         LAN3
4             1                LAN4         LAN4

I noticed that even though the target selected is tl-wr740n-v4, the device built is actually TL-WR741ND-v4 shown on dmesg. That way, the port layout selected on [[http://example.com|External Linkhttps://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ar71xx/base-files/etc/board.d/02_network;hb=d0988235dd277b9a832bbc4b2a100ac6e821f577]] is indeed wrong for this device. That was the only difference that I could find on tl-wr740n-v4, HW 4.28.

What would be the correct fix here, adding a new tl-wr740n-v4 device, or altering the uci default for tl-wr741nd-v4? I can submit the patch, but first would like to know what is preferred.
