Very low bandwidth interfaces detected incorreclty

Very low speed value, ifHighSpeed 0 considered as erroneous and takes old values.

Fixed in r13804.

A few other tests to confirm funnybusiness - it only seems to happen at this very low speed.

Configured device interface  bandwidth to 2000 (2kbps) and it detects it properly:

# show | compare 
[edit interfaces ae5 unit 4000]
- bandwidth 200;
+ bandwidth 2k;

Observium Eventlog:
 ae5.4000 Interface changed: [ifSpeed] '200000000' -> '2000'

Configured device interface bandwidth to 20000 (20kbps) and it's properly detected:

# show | compare 
[edit interfaces ae5 unit 4000]
- bandwidth 2k;
+ bandwidth 20k;

Observium Eventlog:

 ae5.4000 Interface changed: [ifSpeed] '2000' -> '20000'

Set bandwidth back to 200bps and it goes back to 200Mbps:

# show | compare 
[edit interfaces ae5 unit 4000]
- bandwidth 2k;
+ bandwidth 200;

Observium Eventlog:

 ae5.4000 Interface changed: [ifSpeed] '20000' -> '200000000'

Relevant bits of poller.php confirm 200bps:

General questions and device support can be discussed in our Discord channel, click here to join.

Please make and attach additional information about the device:

• full snmp dump from device:

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -Ih -ObentxU <hostname> .1 > myagent.snmpwalk

  snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -Ih -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

  If device not support SNMP version 2c, replace -v2c with -v1.

• If you have problems with discovery or poller processes, please do and attach these debugs:

  ./discovery.php -d -h <device>

  ./poller.php -d -h <device>

• additionally attach device and/or vendor specific MIB files
