From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>
The HWRM_FUNC_QCAPS response indicates the maximum number
of multicast filters that can be supported by this function
on the RX side.
Fixed to use this value instead of the hard coded value 16.
Fixes: d69851df12b2 ("net/bnxt: support multicast filter and set MAC addr")
