arista.eos.eos_prefix_lists fails to gather entries from prefix-lists with two operators

[SteveBarrios]

SUMMARY

The gathered prefix list will be miss any entries where the prefix-list has multiple operators. If there is only one entry / sequence in the prefix-list it will report a prefix-list with no entries, otherwise it will simply skip over the entry with multiple operators.

Example:

ip prefix-list MyList
    seq 10 permit 10.0.0.0/22 ge 22 le 24

OS / ENVIRONMENT

Running against Arista switch:

Hardware version: 11.20
Software image version: 4.31.2F
Architecture: i686
Internal build version: 4.31.2F-35442146.4312F
Internal build ID: 635a071a-386e-447f-942c-bcc34d9ffd3c
Image format version: 3.0
Image optimization: Default

STEPS TO REPRODUCE

1. On your switch, create a prefix-list with a sequence number that contains multiple operators, such as

ip prefix-list stupidtest
    seq 1 permit 10.77.164.0/24
    seq 10 permit 192.168.100.0/24 ge 24 le 26
    seq 20 permit 192.168.200.0/25 ge 27

2. Create a task in your play which registers prefix-lists, such as:

- name: gather configs
  arista.eos.eos_prefix_lists:
    state: gathered
  register: found_terms

EXPECTED RESULTS

In our example, all three sequence numbers should be reported.

ACTUAL RESULTS

The entry will miss the middle "seq 10" entry in the prefix-list above and report as follows:

      - entries:
        - action: permit
          address: 10.77.164.0/24
          sequence: 1
        - action: permit
          address: 192.168.200.0/25
          match:
            masklen: 27
            operator: ge
          sequence: 20
        name: stupidtest
