Test-Label: intel-Functional Test-Status: SUCCESS _Functional PASS_ DPDK git repo: dpdk commit 508d60b518bd6870f906285c689c9508c57e9dd4 Author: Morten Brørup Date: Sat Aug 23 06:30:02 2025 +0000 mbuf: optimize reset of reinitialized mbufs An optimized function for resetting a bulk of newly allocated reinitialized mbufs (a.k.a. raw mbufs) was added. Compared to the normal packet mbuf reset function, it takes advantage of the following two details: 1. The 'next' and 'nb_segs' fields are already reset, so resetting them has been omitted. 2. When resetting the mbuf, the 'ol_flags' field must indicate whether the mbuf uses an external buffer, and the 'data_off' field must not exceed the data room size when resetting the data offset to include the default headroom. Unlike the normal packet mbuf reset function, which reads the mbuf itself to get the information required for resetting these two fields, this function gets the information from the mempool. This makes the function write-only of the mbuf, unlike the normal packet mbuf reset function, which is read-modify-write of the mbuf.
