    ifconfig: fix reporting optics on most 100g interfaces
    
    This fixes a bug where optics on 100G and faster NICs
    were not properly reported.
    
    The problem is that we pull the string from the correct
    table in ifconfig_sfp_physical_spec only when sfp_eth_1040g
    contains the SFP_ETH_1040G_EXTENDED bit.  However, we were
    never saving that bit when it was encountered.  This change
    records that bit into sfp_eth_1040g, allowing us to later
    select the appropriate ID string.
    
    This should cause most 100G interfaces to stop being identified
    as "unknown" in the "plugged" output of ifconfig -v, and to
    start being identified as what they really are.
    
    Example output from a Chelsio T6 with SR4 optics in one port
    and DR1 optics in another:
    
    Before:
    plugged: QSFP28 Unknown (MPO 1x12 Parallel Optic)
    plugged: QSFP28 Unknown (LC)
    
    After:
    plugged: QSFP28 100GBASE-SR4 or 25GBASE-SR (MPO 1x12 Parallel Optic)
    plugged: QSFP28 100GBASE-DR (LC)
