Paul Donald 677edb0bbc lldpd: add custom-tlv handling 
Do not verify the format of TLV. Leave that to lldpd.

These lldpd config entries:

config custom-tlv
	list ports 'eth0'
	option tlv 'replace oui 33,44,55 subtype 254 oui-info 55,55,55,55,55'

config custom-tlv
	option tlv 'oui 33,44,44 subtype 232'
	list ports 'br-lan'
	list ports 'eth0'

config custom-tlv # oui-info truncated
	option tlv 'add oui 33,44,33 subtype 66 oui-info 5555555555'

config custom-tlv
	option tlv 'add oui 33,44,31 subtype 44'

config custom-tlv # invalid oui
	option tlv 'add oui 3322 subtype 79'

config custom-tlv # invalid oui
	option tlv 'oui 3312 subtype 74'

Produce the following lldpd.conf content:

configure ports eth0 lldp custom-tlv replace oui 33,44,55 subtype 254 oui-info 55,55,55,55,55
configure ports br-lan,eth0 lldp custom-tlv oui 33,44,44 subtype 232
configure lldp custom-tlv add oui 33,44,33 subtype 66 oui-info 5555555555
configure lldp custom-tlv add oui 33,44,31 subtype 44
configure lldp custom-tlv add oui 3322 subtype 79
configure lldp custom-tlv oui 3312 subtype 74

And lldpd (v1.0.13 on v22) logs the following:

Sat Mar 16 19:11:39 2024 daemon.info lldpd[10916]: custom TLV op replace oui 33:44:55 subtype fe
Sat Mar 16 19:11:39 2024 daemon.info lldpd[10916]: custom TLV op add oui 33:44:44 subtype e8
Sat Mar 16 19:11:39 2024 daemon.info lldpd[10916]: custom TLV op add oui 33:44:33 subtype 42
Sat Mar 16 19:11:39 2024 daemon.info lldpd[10916]: custom TLV op add oui 33:44:33 subtype 42
Sat Mar 16 19:11:39 2024 daemon.info lldpd[10916]: custom TLV op add oui 33:44:31 subtype 2c
Sat Mar 16 19:11:39 2024 daemon.info lldpd[10916]: custom TLV op add oui 33:44:31 subtype 2c
Sat Mar 16 19:11:39 2024 daemon.warn lldpcli[10915]: invalid OUI value '3322'
Sat Mar 16 19:11:39 2024 daemon.info lldpcli[10915]: an error occurred while executing last command
Sat Mar 16 19:11:39 2024 daemon.warn lldpcli[10915]: invalid OUI value '3312'
Sat Mar 16 19:11:39 2024 daemon.info lldpcli[10915]: an error occurred while executing last command
Sat Mar 16 19:11:39 2024 daemon.info lldpcli[10915]: lldpd should resume operations

( The last two TLV are invalid: their oui must be three hex bytes, comma
separated. Only the first hex byte of oui-info 5555555555 is used )

Depends on #14867 and its release version bump

Tested on: 22.03.6
