/* 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.
