fix_vlan.sh: Refactor script to allow dynamic EntityID instead of hard-coded 4354/4363

[rtsp]

My ISPs EntityID is different from the script so I adjust the script to work on any EntityID instead of hard-coded 4354/4363.

This script was tested on:

• Hardware: ODI DFP-34X-2C2 (STICK3V06)
• Firmware: M110_sfp_ODI_220923.tar
  • Modified by adding /etc/init.d/rc35 and /etc/scripts/fix_vlan.sh to the firmware

Everying working as expected after running the script and set FwdOp to 0x02

I been wondering what "FwdOP" means... mine was 0x10

I'm not exactly sure but it's stated in the GPON spec here https://www.itu.int/rec/T-REC-G.984.4 refer to clause 9.3.11

This document also explained almost every omcicli output if anyone interest
