    if_bnxt: add bnxt_compat.h version-compat shim
    
    Add bnxt_compat.h, a small __FreeBSD_version-gated compatibility
    shim: if_getmtu()/if_name()/if_getsoftc()/if_getflags() fallbacks for
    pre-1500000, and a config-task vs. config-gtask abstraction over the
    iflib API split at 1403000. On this branch's FreeBSD version it also
    unconditionally enables KTLS_IFLIB_SUPPORT/KTLS_REC_SEQ_NUMBER, which
    the upcoming kTLS patch depends on.
