commit 30416d4e827341be32c3e415f16c73f252a68d85 Author: Hans Petter Selasky <[email protected]> AuthorDate: 2021-06-16 13:01:58 +0000 Commit: Hans Petter Selasky <[email protected]> CommitDate: 2021-07-12 12:22:34 +0000 mlx4ib and mlx5ib: Set slid to zero in Ethernet completion struct IB spec says that a lid should be ignored when link layer is Ethernet, for example when building or parsing a CM request message (CA17-34). However, since ib_lid_be16() and ib_lid_cpu16() validates the slid, not only when link layer is IB, we set the slid to zero to prevent false warnings in the kernel log.
