Hi luo jie, I'm a free developer who was trying to add the ethernet support for IPQ5018[1]. And I'm also trying to write the same driver in the V2 patch. When I was trying to write this driver, I was also confused about the 'CMN' whcih I can't find any description. But finally in WiFI documents, I found the same word explained as 'Component'. There may be different. But I think this is a better explanation than 'common'. So I named this driver to QCOM_ETH_CMN (Qualcomm Ethernet Component Driver). Hope this can help something.
