[Patch v4 1/4] RDMA/mana_ib : Rename all mana_ib_dev type variables to mib_dev

From: sharmaajay
Date: Tue Aug 22 2023 - 11:48:00 EST

From: Ajay Sharma <sharmaajay@xxxxxxxxxxxxx>

This patch does not introduce any functional changes. It
creates naming convention to distinguish especially when
used in the same function.Renaming all mana_ib_dev type
variables to mib_dev to have clean separation between
eth dev and ibdev variables.
