lan743x: Remove MAC Reset from initialization

2019-01-13T08:51:03+00:00

[ Upstream commit e0e587878f538c9e3400219b6c516b8199dc2042 ] The MAC Reset was noticed to erase important EEPROM settings. It is also unnecessary since a chip wide reset was done earlier in initialization, and that reset preserves EEPROM settings. There for this patch removes the unnecessary MAC specific reset.

lan743x: Expand phy search for LAN7431

2019-01-13T08:51:02+00:00

[ Upstream commit 0db7d253e9f0ff1a41c602429bea93df221be6ed ] The LAN7431 uses an external phy, and it can be found anywhere in the phy address space. This patch uses phy address 1 for LAN7430 only. And searches all addresses otherwise. Signed-off-by: Bryan Whitehead Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

lan743x: fix return value for lan743x_tx_napi_poll

2018-12-05T18:31:58+00:00

[ Upstream commit cc5922054131f9abefdc0622ae64fc55e6b2671d ] The lan743x driver, when under heavy traffic load, has been noticed to sometimes hang, or cause a kernel panic. Debugging reveals that the TX napi poll routine was returning the wrong value, 'weight'. Most other drivers return 0. And call napi_complete, instead of napi_complete_done. Additionally when creating the tx napi poll routine. Changed netif_napi_add, to netif_tx_napi_add. Updates for v3: changed 'fixes' tag to match defined format Updates for v2: use napi_complete, instead of napi_complete_done in lan743x_tx_napi_poll use netif_tx_napi_add, instead of netif_napi_add for registration of tx napi poll routine fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver") Signed-off-by: Bryan Whitehead Signed-off-by: David S.

lan743x: Enable driver to work with LAN7431

2018-12-05T18:31:58+00:00

[ Upstream commit 4df5ce9bc03e47d05f400e64aa32a82ec4cef419 ] This driver was designed to work with both LAN7430 and LAN7431. The only difference between the two is the LAN7431 has support for external phy. This change adds LAN7431 to the list of recognized devices supported by this driver.

net: ethernet: Fix a unused function warning.

Fix the following compile warning: drivers/net/ethernet/microchip/lan743x_main.c:2964:12: warning: lan743x_pm_suspend defined but not used [-Wunused-function] static int lan743x_pm_suspend(struct device *dev) drivers/net/ethernet/microchip/lan743x_main.c:2987:12: warning: lan743x_pm_resume defined but not used [-Wunused-function] static int lan743x_pm_resume(struct device *dev) Signed-off-by: zhong jiang Signed-off-by: David S.

net: lan743x_ptp: convert to ktime_get_clocktai_ts64

2018-08-19T17:56:40+00:00

timekeeping_clocktai64() has been renamed to ktime_get_clocktai_ts64() for consistency with the other ktime_get_* access functions. Rename the new caller that has come up as well. Question: this is the only ptp driver that sets the hardware time to the current system time in TAI. Why does it do that? Signed-off-by: Arnd Bergmann Signed-off-by: David S. Miller

Those #ifdef checks are hard to get right, replace them all with IS_ENABLED() checks that leave the same code visible to the compiler but let it optimize out the unused bits based on the configuration.
