Fixing double ip assignment

   - `nvme_tcp`/`nvme_fabrics` must be loaded before `/dev/nvme-fabrics` exists
     (dracut's `nvmf` module does this in a normal boot; at `rd.break` modprobe
     manually).
+  - **Don't double-configure the NIC in test mode.** With `ip=dhcp` on the
+    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`,
+    which (a) raced dracut → `Error: ipv4: Address already assigned`, and (b)
+    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
+    is what masked it). **Fixed:** the bypass branch no longer touches the NIC;
+    `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:**
