commit 214b3369ab9b0a6f28d6c970220c209417edbc65 upstream. Clang static analysis reports this problem mtk_eth_soc.c:394:7: warning: Branch condition evaluates to a garbage value if (err) ^~~ err is not initialized and only conditionally set.

2021-06-03net: ethernet: mtk_eth_soc: Fix packet statistics support for MT7628/88Stefan Roese
[ Upstream commit ad79fd2c42f7626bdf6935cd72134c2a5a59ff2d ] The MT7628/88 SoC(s) have other (limited) packet counter registers than currently supported in the mtk_eth_soc driver. This patch adds support for reading these registers, so that the packet statistics are correctly updated. Additionally the defines for the non-MT7628 variant packet counter registers are added and used in this patch instead of using hard coded values.

2019-07-04net: ethernet: mediatek: Fix overlapping capability bits.René van Dorst
Both MTK_TRGMII_MT7621_CLK and MTK_PATH_BIT are defined as bit 10. This can causes issues on non-MT7621 devices which has the MTK_PATH_BIT(MTK_ETH_PATH_GMAC1_RGMII) and MTK_TRGMII capability set. The wrong TRGMII setup code can be executed. The current wrongly executed code doesn’t do any harm on MT7623 and the TRGMII setup for the MT7623 SOC side is done in MT7530 driver So it wasn’t noticed in the test. Move all capability bits in one enum so that they are all unique and easy to expand in the future. Because mtk_eth_path enum is merged in to mkt_eth_capabilities, the variable path value is no longer between 0 to number of paths, mtk_eth_path_name can’t be used anymore in this form. Convert the mtk_eth_path_name array to a function to lookup the pathname. The old code walked thru the mtk_eth_path enum, which is also merged with mkt_eth_capabilities. Expand array mtk_eth_muxc so it can store the name and capability bit of the mux. Convert the code so it can walk thru the mtk_eth_muxc array.

2019-04-01net: move skb->xmit_more hint to softnet dataFlorian Westphal
There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

Except you have a specific need you normally don't need to manually fiddle with this. - phy_start_aneg() is called implicitly by the phylib state machine, you shouldn't call it manually except you have a good excuse. - netif_carrier_on/netif_carrier_off in mtk_phy_link_adjust() isn't needed. It's done by phy_link_change() in phylib.

2018-11-11net: ethernet: Convert phydev advertize and supported from u32 to link modeAndrew Lunn
There are a few MAC/PHYs combinations which now support > 1Gbps. These may need to make use of link modes with bits > 31. Thus their supported PHY features or advertised features cannot be implemented using the current bitmap in a u32. Convert to using a linkmode bitmap, which can support all the currently devices link modes, and is future proof as more modes are added.

2018-09-12net: ethernet: Fix up drivers masking pause supportAndrew Lunn
PHY drivers don't indicate they support pause. They expect MAC drivers to enable its support if the MAC has the needed hardware. Thus MAC drivers should not mask Pause support, but enable it.

2018-07-29net-next: mediatek: cleanup unnecessary get chip id and its userSean Wang
Since driver is devicetree-based, all device type and charateristic can be determined by the compatible string and its data. It's unnecessary to create another dependent function to check chip ID and then decide whether the specific funciton is being supported on a certain device. It can be totally replaced by the existing flag, so a cleanup is made by removing the function and the only user, HWLRO. MT2701 also have a missing HWLRO support in old code, so add it the same patch. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
