CONTAP-53314: Tx total errors count of an interface group port in "ifstat" output might not correlate with respective counts of member ports

• Output of ifstat in section TRANSMIT indicates increasing Total Errors for interface group, but not for its underlying physical member ports.

Example:
    RECEIVE
    Total frames: 72688k | Frames/second: 266 | Total bytes: 207g
    Bytes/second: 760k | Total errors: 0 | Errors/minute: 0
    [...]
    TRANSMIT
    Total frames: 397m | Frames/second: 55169 | Total bytes: 512g
    Bytes/second: 71122k | Total errors: 2720 | Errors/minute: 23
Note: Total errors on TRANSMIT increased

• EMS finds ifgrp interface generate alert vifmgr.cluscheck.crcerrors.
