SFP diagnostics is not into shmem (nor SNMP)
This information might be useful to check the power of the optical link:
However we always have has_sfp_diag=0 in shmem and all related fields are not existent.
calib.sfp.part_num: "AXGD-3454-0531"
calib.sfp.vendor_serial: "AX18470005178"
...
ep_base: 0x00030c00
has_sfp_diag: 0
Even if we can retrieve these values with
wrs_sfp_dump -d -I
