  "message": "[roll] Roll fuchsia [netstack3] Add chunked ring buffer impl for pcaps\n\nAdd a ring buffer implementation for supporting storing packet\ncapture data. The ring buffer has a defined block size, and\nstores \"boundary indices\" whenever a write results in the tail pointer\nexceeding the block size. This is so that when bytes need to be dropped\nfrom the ring buffer, bytes up to the next boundary is dropped. This\nensures that when the pcapng Enhanced Packet Blocks are written to the\nring buffer, reclaiming space from the buffer only drops full\npacket blocks at a time.\n\nOriginal-Bug: 485274945\nOriginal-Reviewed-on: https://fuchsia-review.googlesource.com/c/fuchsia/+/1562199\nOriginal-Revision: ecdca9cbb5b0ee61ec04745ce3511c2082897dcf\nGitOrigin-RevId: 344e77b4df68451532bc3352a9eee41011f7ae2a\nChange-Id: Ie59f987e0034d7d6e8769b9956198cf282880a01\n",
