Subject: [net-next 03/16] net/mlx5e: Encapsulate updating netdev queues into a function
Date: Tue, 25 Feb 2020 17:12:33 -0800	[thread overview]
Message-ID: <20200226011246.70129-4-saeedm@mellanox.com> (raw)
In-Reply-To: <20200226011246.70129-1-saeedm@mellanox.com>

From: Maxim Mikityanskiy <maximmi@mellanox.com>

As a preparation for one of the following commits, create a function to
encapsulate the code that notifies the kernel about the new amount of
RX and TX queues. The code will be called multiple times in the next
commit.
