Date: Thu, 6 Jun 2019 14:06:07 +0300 [thread overview]
Message-ID: <20190606110609.11588-2-leon@kernel.org> (raw)
In-Reply-To: <20190606110609.11588-1-leon@kernel.org>
From: Maor Gottlieb <maorg@mellanox.com>
Add API to get the current Eswitch encap mode.
It will be used in downstream patches to check if
flow table can be created with encap support or not.
