Subject: [PATCH V2 07/10] ath11k: add a struct to pass parameters into ath11k_wmi_vdev_up
Date:   Mon,  6 Jul 2020 13:52:16 +0200
Message-Id: <20200706115219.663650-7-john@phrozen.org>

Precedence: bulk

When setting up a multiple bssid we need to pass additional parameters to
the FW. Doing this as individual parameters would make the call signature
very long. Use an intermediate struct instead and adjust all callees to
make use of it.
