[dpdk-dev] [PATCH 6/6] net/ice/base: fix for and/or bitmap routines

[Qi Zhang <qi.z.zhang@intel.com>]

There was an issue with ice_and_bitmap and ice_or_bitmap when
dealing with bit array sizes that are not even multiples of 32,
where some of relevant bits in the highest 32 bits were being
cleared. This patch fixes those problems.
