From: Or Gerlitz Date: Tue, 24 Jan 2017 11:02:39 +0000 (+0200) Subject: IB: Query ports via the core instead of direct into the driver X-Git-Tag: v4.11-rc1~94^2~4 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c4550c63b363914071d63a36e5bedcfe22057940;p=thirdparty%2Flinux.git IB: Query ports via the core instead of direct into the driver Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers. This patch doesn't add any new functionality.
