Subject: [PATCH V2 net-next 6/6] net: hns3: replace macro of max qset number with specification
Date: Fri, 5 Feb 2021 16:32:49 +0800	[thread overview]
Message-ID: <1612513969-9278-7-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1612513969-9278-1-git-send-email-tanhuazhong@huawei.com>

From: Guangbin Huang <huangguangbin2@huawei.com>

The max qset number is a fixed value now and it is defined by a macro.
In order to support other value in different kinds of device, it is
better to use specification queried from firmware to replace macro.
