+
+Because the bootloader (CFE) is not initializing the Read-ahead cache properly
+on the second thread (TP1). Since the RAC was not initialized properly, we
+should avoid flushing it at the risk of corrupting the instruction stream as
+seen in the trace above.

+ v3: add changes suggested by Florian:
+   - Switch to a bool and remove unneeded initialization.
+   - Remove if from bcm6358_quirks().
+   - Improve commit description and bcm6358_quirks() comment.
+ v2: check if we're running on TP1 and invert logic.

+
+When BCM63xx internal switches are connected to switches with a 4-byte
+Broadcom tag, it does not identify the packet as VLAN tagged, so it adds one
+based on its PVID (which is likely 0).
+Right now, the packet is received by the BCM63xx internal switch and the 6-byte
+tag is properly processed. The next step would to decode the corresponding
+4-byte tag. However, the internal switch adds an invalid VLAN tag after the
+6-byte tag and the 4-byte tag handling fails.
+In order to fix this we need to remove the invalid VLAN tag after the 6-byte
+tag before passing it to the 4-byte tag decoding.
