Subject: sfc: Fix MCDI structure field lookup
From: Ben Hutchings <[email protected]>
[ Upstream commit 0a6e5008a9df678b48f8d4e57601aa4270df6c14 ]
The least significant bit number (LBN) of a field within an MCDI
structure is counted from the start of the structure, not the
containing dword. In MCDI_ARRAY_FIELD() we need to mask it rather
than using the usual EFX_DWORD_FIELD() macro.
