> The max chained Tx BDs of latest ENETC (i.MX95 ENETC, rev 4.1) has been
> increased to 63, but since the range of MAX_SKB_FRAGS is 17~45, so for
> i.MX95 ENETC and later revision, it is better to set ENETC4_MAX_SKB_FRAGS
> to MAX_SKB_FRAGS.
> 
> In addition, add max_frags in struct enetc_drvdata to indicate the max
> chained BDs supported by device. Because the max number of chained BDs
> supported by LS1028A and i.MX95 ENETC is different.
