[2/7] net/bnxt: use correct number of RSS contexts for thor
Checks
Commit Message
From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>
BCM57500-based adapters use a variable number of RSS contexts
depending upon the number of receive rings in use. The current
implementation is erroneously using the maximum possible number
of RSS contexts instead of the actual number allocated when
setting up RSS tables in the adapter. Fix by using the actual
number of allocated contexts.
Fixes: 38412304b50a ("net/bnxt: enable RSS for thor-based controllers")
