Subject: [PATCH iproute2-next v2 2/2] devlink: Expose port split ability
Date: Thu, 30 Jul 2020 17:33:18 +0300	[thread overview]
Message-ID: <20200730143318.1203-3-danieller@mellanox.com> (raw)
In-Reply-To: <20200730143318.1203-1-danieller@mellanox.com>

Add a new attribute that indicates the port split ability to devlink port.

Expose the attribute to user space as RO value, for example:

$devlink port show swp1
pci/0000:03:00.0/61: type eth netdev swp1 flavour physical port 1
splittable false lanes 1
