Subject: [PATCH net-next v5 2/3] net: mana: Move current_speed debugfs file to mana_init_port()
Date: Thu,  2 Apr 2026 11:26:56 -0700	[thread overview]
Message-ID: <20260402182704.2474739-3-ernis@linux.microsoft.com> (raw)
In-Reply-To: <20260402182704.2474739-1-ernis@linux.microsoft.com>

Move the current_speed debugfs file creation from mana_probe_port() to
mana_init_port(). The file was previously created only during initial
probe, but mana_cleanup_port_context() removes the entire vPort debugfs
directory during detach/attach cycles. Since mana_init_port() recreates
the directory on re-attach, moving current_speed here ensures it survives
these cycles.

Fixes: 75cabb46935b ("net: mana: Add support for net_shaper_ops")
