Subject[PATCH AUTOSEL 4.18 046/100] qed: Fix shmem structure inconsistency between driver and the mfw.
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.)
