commit 4beb83095351b46dcc26e0475341d6d96ce80fc5
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>

    Split ROUTER_REQUIRED_MIN_BANDWIDTH into RELAY_ and BRIDGE_ variants
    
    Also raise those minima from 20 to 75 and 50 respectively.
    
    Closes ticket 13822.

+  o Minor features:
+    - Use separate minimum bandwidth values for the configurations of
+      relays and bridges. Raise the minimum configured bandwidth for
+      bridges to 50 KiB/sec and for relays to 75 KiB/sec. (The old
+      values were 20 KiB/sec.) Closes ticket 13822.
