Date: Tue, 16 Oct 2018 00:11:27 -0400 Message-Id: <20181016041221.135528-46-sashal@kernel.org> In-Reply-To: <20181016041221.135528-1-sashal@kernel.org> References: <20181016041221.135528-1-sashal@kernel.org> List-ID: From: Sudarsana Reddy Kalluru [ Upstream commit 5f672090e44f4951084c5e1d6b0668a5fc422af8 ] The structure shared between driver and the management FW (mfw) differ in sizes. This would lead to issues when driver try to access the structure members which are not-aligned with the mfw copy e.g., data_ptr usage in the case of mfw_tlv request. Align the driver structure with mfw copy, add reserved field(s) to driver structure for the members not used by the driver. Fixes: dd006921d67f ("qed: Add MFW interfaces for TLV request support.)
