/* This flag enables the retrofitted support for old RAS compression and
** coherency, i.e. the scheme available on WFW311 and NT31 clients. This** support was added post-NT35 for inclusion in the NT-PPC release. It looks** to NDISWAN like a hardware specific compression. (SteveC)**** Note: The 'CompressBCast' feature that allows user to control whether** broadcast frames are compressed is not supported here because the** ethernet header (from which NT31 determined a frame was a broadcast)** is not available in the new NDISWAN interface. This was a tuning** feature, where data not likely to repeat (broadcasts) were eliminated** from the pattern buffer. There should not be any functional problems** simply compressing broadcast frames since the receiver determines** whether decompression is required regardless of this setting. Given** this, it's a mystery why TommyD bothered negotiating this with the** peer. To avoid hitting non-default code paths on the clients we will** simply negotiate the old default (no compression), but will still** compress everything on the outgoing path.*/
