Fixing double ip assignment

   - `nvme_tcp`/`nvme_fabrics` must be loaded before `/dev/nvme-fabrics` exists

     manually).

+    cmdline, dracut's network module brings the NIC up AND emits the "online"
+    event that the `nvmf` module's `initqueue/online` hook waits on to run
+    `nvme connect-all`. The `rd.dot1x=0` bypass used to *also* `ifup $NIC`,

+    didn't fire the nvmf online hook, so the namespace never auto-connected and
+    boot spun on `/dev/mapper/root` forever (manual `connect-all` worked, which

+    `ip=dhcp` owns networking and triggers nvmf autoconnect. (The secure path
+    still addresses macsec0 itself — dracut doesn't know about that interface.)
   - The target Rocky 9 kernel's erofs is built **without
     `CONFIG_EROFS_FS_ZIP`** — mounting a compressed image fails `erofs: lz4
     algorithm isn't enabled`, which silently blocks the root mount. **Fixed:**
