Nothing lives outside the repo: the bench ixgbe driver source moves in tracked at kernel/ixgbe-sff/ (build artifacts gitignored, load-ixgbe repointed, module build verified from the new home — the reg_ops/ts_bench bench extras are finally versioned), the ice sff_i2c patch is vendored at docs/nics/e810/ice-sff-i2c.patch with its out-of-tree build recipe (TRACE_INCLUDE_PATH fixup, version-matched Makefile), the e810 NVM flash logistics land in the e810 README (exact package name, rollback -m B49691D578EC into the inactive bank, post-flash inventory failing until power cycle is the expected tell), and every ~/work/phydiag-work pointer becomes an inline statement; phydiag-work, ice-sff, e810nvm and the wiitekphy CLI (a duplicate of documented transport+protocol) are deleted
