set cable length of backplane ports to 1m

[zhixzhu]

Why I did it

backplane ports cable length need to be specified.

How I did it

separated handling for the specific port name.

How to verify it

Used "sonic-cfggen" to generate buffer config, and verified cable length of backplane ports is 1m, other ports default length.

@lguohan There is 1 workflow awaiting approval, could you help approve it?
The failure happened when running script bgp/test_bgp_fact.py, changing the cable length of backplane ports should not have any impact on it, how to rerun this test?

Does cherry-pick of master has conflict ?

[zhixzhu]

The failure log is:

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.1 (= 1.1.1n-0+deb11u4) but 1.1.1n-0+deb11u3 is to be installed
E: Unable to correct problems, you have held broken packages.

@lguohan @abdosi Could you help rerun the pipeline?

Does cherry-pick of master has conflict ?

Yes, the type of argument in src/sonic-config-engine/tests/test_multinpu_cfggen.py run_script is different between master and 202205 branch.

@abdosi Pipeline still failed at:

The failure is not related with this PR's code change, how to proceed with it? Any suggestions?

[zhixzhu]

@abdosi I checked the recent PRs to target branch 202205, they all have the same pipeline failure on the "Build marvell_armhf", including open PRs and merged PRs, e.g. #13778

Could you help merge my PR in this case?

[zhixzhu]

@abdosi Any suggestions on how to proceed?
