Subject: [PATCH AUTOSEL 4.19 240/671] nfp: fix simple vNIC mailbox length

From: Dirk van der Merwe <dirk.vandermerwe@...ronome.com>

[ Upstream commit eaab2d2d0fe4393b040dbf3922e18cd2ab7d6b85 ]

The simple vNIC mailbox length should be 12 decimal and not 0x12.
Using a decimal also makes it clear this is a length value and not
another field within the simple mailbox defines.

Found by code inspection, there are no known firmware configurations
where this would cause issues.

Fixes: 527d7d1b9949 ("nfp: read mailbox address from TLV caps")
