[PATCH 6.0 0584/1073] RDMA/irdma: Report the correct link speed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shiraz Saleem <shiraz.saleem@xxxxxxxxx>

[ Upstream commit 4eace75e0853273755b878ffa9cce6de84df975a ]

The active link speed is currently hard-coded in irdma_query_port due
to which the port rate in ibstatus does reflect the active link speed.

Call ib_get_eth_speed in irdma_query_port to get the active link speed.

Fixes: b48c24c2d710 ("RDMA/irdma: Implement device supported verb APIs")
