-Subject: [PATCH 20/22] enic: fix Rx descriptor limit
-
- On initialization, the rq descriptor count was set to the limit
- of the vic. When the requested number of rx descriptors was
- less than this count, enic_alloc_rq() was incorrectly setting
- the count to the lower value. This results in later calls to
- enic_alloc_rq() incorrectly using the lower value as the adapter
- limit.
-
- Fixes: fefed3d1e62c ("enic: new driver")
