net: bcmasp: Fix network filter wake for asp-3.0

2026-01-30T09:32:21Z

[ Upstream commit bbb11b8d758d17a4ce34b8ed0b49de150568265b ] We need to apply the tx_chan_offset to the netfilter cfg channel or the output channel will be incorrect for asp-3.0 and newer.

net: bcmasp: Add support for asp-v3.0

2025-04-24T23:59:53Z

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.

net: bcmasp: Remove support for asp-v2.0

2025-04-24T23:59:52Z

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.

net: bcmasp: Keep buffers through power management

2024-03-01T09:22:50Z

There is no advantage of freeing and re-allocating buffers through suspend and resume. This waste cycles and makes suspend/resume time longer. We also open ourselves to failed allocations in systems with heavy memory fragmentation. Signed-off-by: Justin Chen Acked-by: Florian Fainelli Signed-off-by: David S. Miller

net: bcmasp: Add support for ASP 2.2

2024-03-01T09:22:49Z

ASP 2.2 improves power savings during low power modes. A new register was added to toggle to a slower clock during low power modes. EEE was broken for ASP 2.0/2.1. A HW workaround was added for ASP 2.2 that requires toggling a chicken bit. Signed-off-by: Justin Chen Acked-by: Florian Fainelli Signed-off-by: David S. Miller

ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side

2024-01-31T12:30:47Z

In order to pass EEE link modes beyond bit 32 to userspace we have to complement the 32 bit bitmaps in struct ethtool_eee with linkmode bitmaps. Therefore, similar to ethtool_link_settings and ethtool_link_ksettings, add a struct ethtool_keee. In a first step it's an identical copy of ethtool_eee. This patch simply does a s/ethtool_eee/ethtool_keee/g for all users. No functional change intended.

net: ethernet: bcmasp: fix possible OOB write in bcmasp_netfilt_get_all_active()

2023-09-11T07:26:10Z

rule_locs is allocated in ethtool_get_rxnfc and the size is determined by rule_cnt from user space. So rule_cnt needs to be check before using rule_locs to avoid OOB writing or NULL pointer dereference.

net: bcmasp: Prevent array undereflow in bcmasp_netfilt_get_init()

The "loc" value comes from the user and it can be negative leading to an an array underflow when we check "priv->net_filters[loc].claimed". Fix this by changing the type to u32.
