Subject: re: net/mlx4_core: Capping number of requested MSIXs to MAX_MSIX

> We currently manage IRQs in pool_bm which is a bit field of MAX_MSIX bits.
> Thus, allocating more than MAX_MSIX interrupts can't be managed in pool_bm.
> Fixing this by capping number of requested MSIXs to MAX_MSIX.

Carol, Matan, could U2 elaborate where/when the bug hits us?


Also, missing Fixes: line here with the offending commit ID so we can
