[PATCH net-next v2 0/8] net: bcmasp: Add v3.0 and remove v2.0

[PATCH net-next v2 0/8] net: bcmasp: Add v3.0 and remove v2.0

[Justin Chen]

asp-v2.0 had one supported SoC that never saw the light of day.
Given that it was the first iteration of the HW, it ended up with
some one off HW design decisions that were changed in futher iterations
of the HW. We remove support to simplify the code and make it easier to
add future revisions.

Add support for asp-v3.0. asp-v3.0 reduces the feature set for cost
savings. We reduce the number of channel/network filters. And also
remove some features and statistics.

[PATCH net-next v2 3/8] net: bcmasp: Remove support for asp-v2.0

[Justin Chen]

The SoC that supported asp-v2.0 never saw the light of day. asp-v2.0 has
quirks that makes the logic overly complicated. For example, asp-v2.0 is
the only revision that has a different wake up IRQ hook up. Remove asp-v2.0
support to make supporting future HW revisions cleaner.

[PATCH net-next v2 7/8] net: bcmasp: Add support for asp-v3.0

[Justin Chen]

The asp-v3.0 is a major HW revision that reduced the number of
channels and filters. The goal was to save cost by reducing the
feature set.

Changes for asp-v3.0
- Number of network filters were reduced.
- Number of channels were reduced.
- EDPKT stats were removed.
- Fix a bug with csum offload.
