The branch stable/13 has been updated by manu: URL: https://cgit.FreeBSD.org/src/commit/?id=d37a33f52c369f071d036d3cf8940215f682c636 commit d37a33f52c369f071d036d3cf8940215f682c636 Author: Emmanuel Vadot <manu@FreeBSD.org> AuthorDate: 2021-12-30 08:47:06 +0000 Commit: Emmanuel Vadot <manu@FreeBSD.org> CommitDate: 2022-01-13 07:59:03 +0000 loader: tftp: Copy the first block into the cache tftp_open reads the first block so copy it in the cached data. If we have more than one block (i.e. we called tftp_read before tftp_preload) simply just reset the transfer.
