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: bcm: asp2: remove tx_lpi_enabled

2025-01-15T21:17:56Z

Phylib maintains a copy of tx_lpi_enabled, which will be used to populate the member when phy_ethtool_get_eee(). Therefore, writing to this member before phy_ethtool_get_eee() will have no effect. Remove it. Also remove setting our copy of info->eee.tx_lpi_enabled which becomes write-only.

net: broadcom: use ethtool string helpers

2024-11-07T01:51:02Z

The latter is the preferred way to copy ethtool strings. Avoids manually incrementing the pointer. Cleans up the code quite well.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

net: bcmasp: remove eee_enabled/eee_active in bcmasp_get_eee()

2024-02-07T17:03:38Z

bcmasp_get_eee() sets edata->eee_active and edata->eee_enabled from its own copy, and then calls phy_ethtool_get_eee() which in turn will call genphy_c45_ethtool_get_eee(). genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active with its own interpretation from the PHYs settings and negotiation result. Therefore, setting these members in bcmasp_get_eee() is redundant, and can be removed. This also makes intf->eee.eee_active unnecessary, so remove this and use a local variable where appropriate.
