Subject: [PATCH v3 05/25] net/axgbe: disable interrupts during device removal
Date: Tue, 4 Jun 2024 17:41:37 +0530	[thread overview]
Message-ID: <20240604121157.3052-5-venkatkumar.ande@amd.com> (raw)
In-Reply-To: <20240604121157.3052-1-venkatkumar.ande@amd.com>

From: Venkat Kumar Ande <VenkatKumar.Ande@amd.com>

Hardware interrupts are enabled during the init, however,
they are not disabled during close.

Disable all hardware interrupts during close operation to avoid any
issues.

Fixes: 9e890103267e ("net/axgbe: add Rx/Tx setup")
