Subject: [PATCH net 1/6] net: bcmasp: fix mib counters struct alignment with ethtool stats
Date: Tue, 22 Sep 2026 15:16:25 -0700	[thread overview]
Message-ID: <20260922221630.3864427-2-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20260922221630.3864427-1-florian.fainelli@broadcom.com>

When EDPKT stats were removed in commit e9f31435ee7d ("net: bcmasp: Add
support for asp-v3.0"), the corresponding entries were removed from
bcmasp_gstrings_stats in bcmasp_ethtool.c, but the edpkt_* fields were
left at the beginning of struct bcmasp_mib_counters in bcmasp.h.

Because bcmasp_update_mib_counters() and bcmasp_get_ethtool_stats() index
into struct bcmasp_mib_counters sequentially based on the order of
bcmasp_gstrings_stats, this 16-byte offset caused hardware statistics
to be written to the wrong struct members and software counters to be
read from incorrect offsets (and reading out-of-bounds at the end of the
struct).

Remove the obsolete edpkt_* fields from struct bcmasp_mib_counters so
that it aligns with bcmasp_gstrings_stats.

Fixes: e9f31435ee7d ("net: bcmasp: Add support for asp-v3.0")
