From 25baace94298bbe50a91f7b1b7470bf0eb5688fa Mon Sep 17 00:00:00 2001 From: Raymond Mao Date: Fri, 18 Jul 2025 07:16:17 -0700 Subject: bloblist: add API for applying blobs with specified tag Add an API to search for the blobs with specified tag and use the hook function to apply the blob data. Add a helper function to return the inline header size as according to recent spec[1] updates, the actual data can be following an inline header instead of following the TE header immediately.
