ar71xx: fix ethernet on wnr2000-v4
Most people report broken ethernet with upstream. Last year, user "franz.flasch" authored a working mach-file. His patch is outdated so I modernized it. Original patch and user commentary on page 1: https://forum.openwrt.org/viewtopic.php?pid=260861#p260861 I have figured out what the critical differences are between the two that caused upstream ethernet to break. 1) Both ath79_init_mac() functions calls must be invocated before any GMAC init 2) must init GMAC0 before GMAC1 That was enough to get upstream to function, but I wanted to enjoy my confidence having tested franz's patch for a week sucessfully, so I put his whole function in, which only features more differences in order of function calls. An expert should consider these changes, which could pose potential bugs/issues: 1) No longer using the flag AR934X_ETH_CFG_SW_PHY_SWAP in the ath79_setup_ar934x_eth_cfg() call. 2) Possible consequence of no longer explicitly setting ethernet duplex/speed. Review: With this patch, my ethernet and wireless works. Signed-off-by: Michael J. Bazzinotti <mbazzinotti@gmail.com> SVN-Revision: 45633
