From: Thomas Monjalon Date: Wed, 20 Oct 2021 14:55:17 +0000 (+0100) Subject: ethdev: replace bit shifts with macros X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e1823e084255869680322e515b9dcb1c18bcb798;p=dpdk.git ethdev: replace bit shifts with macros The macros RTE_BIT32 and RTE_BIT64 are used to replace bit shifts. The macro UINT64C is also used to replace remaining occurrences of ULL. The bit shifts of ETH_RSS_LEVEL_* are kept for aesthetic reason. The API of rte_mtr and rte_tm is using enums for 64-bit variables. As they are enums, unsigned bit cannot be used.
