Nothing, really. The RN massively outnumbered the German Fleet, subs were more or less not in existence at the time, at least not on a useful scale, and the Germans have no way of helping the Boers at all. At least otl they could manage to funnel a small amount of supplies - with that PoD, not even that.

Long-term, however.... Brits gain their colonies, Germans suffer in Germany somewhat. Expect a French invasion should they start to unravel at all.
