Subject: [PATCH 21.11 3/4] net/hns3: fix LRO offload to report
Date: Thu, 23 Nov 2023 16:05:28 +0800 [thread overview]
Message-ID: <20231123080529.15216-4-lihuisong@huawei.com> (raw)
In-Reply-To: <20231123080529.15216-1-lihuisong@huawei.com>
[ upstream commit a4b2c6815abd3e39daca2e2c93334b813e6a0be4 ]
Some network engines, like part of HIP09, may not support LRO
offload, but this offload capability is also reported to user.
So this patch determines whether driver reports this capability
based on the capabilities from firmware.
In addition, some network engines, like HIP08, always support LRO
offload and their firmware don't report this capability. So this
patch has to move getting revision ID codes to earlier stage and set
default capabilities for these network engines based on revision ID.
Fixes: ab2e2e344163 ("net/hns3: get device capability in primary process")
Fixes: f5ed7d99cf45 ("net/hns3: extract common function to obtain revision ID")
