Subject: [PATCH net-next v4 06/15] mctp: Add device handling and netlink interface
Date: Thu, 29 Jul 2021 10:20:44 +0800 [thread overview]
Message-ID: <20210729022053.134453-7-jk@codeconstruct.com.au> (raw)
In-Reply-To: <20210729022053.134453-1-jk@codeconstruct.com.au>
This change adds the infrastructure for managing MCTP netdevices; we add
a pointer to the AF_MCTP-specific data to struct netdevice, and hook up
the rtnetlink operations for adding and removing addresses.
Includes changes from Matt Johnston <matt@codeconstruct.com.au>.
Signed-off-by: Jeremy Kerr <jk@codeconstruct.com.au>
---
v2:
- controller -> component
v3:
- fix addrinfo dump iteration & error path
- fix non-negative ERR_PTR
- use an array for local EIDs
- remove unnecessary RTM_GETLINK unregister
- add RTM_DELADDR
v4:
- upstream change: set_link_af no longer called with RTNL held
- add kdoc for net_device.mctp_ptr
