[GitHub] [mynewt-core] wes3 opened a new pull request #2075: kernel/os: Add os_mbuf_pack_chains

wes3 opened a new pull request #2075: kernel/os: Add os_mbuf_pack_chains
URL: https://github.com/apache/mynewt-core/pull/2075
 
 
   This commit adds a new API for mbuf handling called os_mbuf_pack_chains.
   This API, given two mbuf chains, will concatenate them and copy data
   as needed so that each mbuf fully utilizes the data buffer in each mbuf.
   Unused mbufs are discarded. This API sacrifices speed for memory and
   may cause a lot of copying to occur within the mbuf chains.
   
   Test code has been written for a number of reasonable cases.
