Support MA5671A SFP GPON

For Developers
25

Dear friends. Thanks for the topic.
The module is good. It has a lot of possibilities and keeps the temperature low. I've struggled a lot to run it with my internet provider. The password, GPON serial number and MAC are encoded using base64 and stored into sfp_a2_info variable. "@" is used as a new line delimiter "\n"

PART 1. BACKUP
Before you start, save your crucial data to backup files.
root@SFP:~# fw_printenv

Save mtd1 partition
user@ubuntu:~$ nc -l -p 1234 > mtd1.bin (listen on the linux PC, port 1234@ 192.168.1.11)
root@SFP:~# cat /dev/mtd1 | nc 192.168.1.11 1234 (execute on MA5671A)

PART 2. PREPARATIONS
Existing data of my module.
Serial Number = HWTC11223344
gpon Password = 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
MAC = 48:57:02:da:be:ef

I will be changing to:
Serial Number = ZTEG87654321
gpon Password = 0xde 0xad 0x11 0x22 0x33 0x44 0x55 0x66 0xbe 0xef
MAC = 49:f2:02:33:7f:11

Transfer modified sfp_a2.txt file back into variable sfp_a2_info
root@SFP:~# fw_setenv sfp_a2_info `cat /tmp/sfp_a2.txt`

PART 4. REVIEW AND TESTING
After reboot I check for new variables
root@SFP:~# fw_printenv sfp_a2_info
