====================
net: dsa: tag_rtl8_4: fixes doc and set keep

This small series addresses two points in the rtl8_4 tagger used by the
realtel rtl8365mb driver.

The first patch updates the documentation of the tag format while the
second patch sets the KEEP flag bit, ensuring that the switch
respects the frame's VLAN format as provided by the kernel.

These patches were previously part of a larger series but are being
submitted independently as they are self-contained and already
received review.
