One write was to DEV_CLOCK_CFG and one was to ANA_PFC_PCF_CFG. Both of these writes referenced the variable "speed" which originally was set to OCELOT_SPEED_{10,100,1000,2500}. These macros expand to values of 3, 2, 1, or 0, respectively. After the update, the variable speed is set to SPEED_{10,100,1000,2500} which expand to 10, 100, 1000, and 2500. So invalid values were getting written to the two registers, which would lead to either a lack of functionality or undefined funcationality. Fixing these values was the intent of v1 of this patch set - submitted as "[PATCH v1 net] net: ethernet: mscc: ocelot: bug fix when writing MAC speed" During that review it was determined that both writes were actually unnecessary. DEV_CLOCK_CFG is a duplicate write, so can be removed entirely. This was accidentally submitted as as a new, lone patch titled "[PATCH v1 net] net: mscc: ocelot: remove buggy duplicate write to DEV_CLOCK_CFG". This is part of what is considered v2 of this patch set. Additionally, the write to ANA_PFC_PFC_CFG is also unnecessary. Priority flow contol is disabled, so configuring it is useless and should be removed. This was also submitted as a new, lone patch titled "[PATCH v1 net] net: mscc: ocelot: remove buggy and useless write to ANA_PFC_PFC_CFG". This is the rest of what is considered v2 of this patch set. v3 Identical to v2, but fixes the patch numbering to v3 and submitting the two changes as a patch set. v2 Note: I misunderstood and submitted two new "v1" patches instead of a single "v2" patch set. - Remove the buggy writes altogher ==================== Signed-off-by: David S.
