r8169: avoid link-up interrupt issue on RTL8106e if user enables ASPM

2021-07-19T08:00:58Z

[ Upstream commit 1ee8856de82faec9bc8bd0f2308a7f27e30ba207 ] It has been reported that on RTL8106e the link-up interrupt may be significantly delayed if the user enables ASPM L1. Per default ASPM is disabled. The change leaves L1 enabled on the PCIe link (thus still allowing to reach higher package power saving states), but the NIC won't actively trigger it.

r8169: Avoid memcpy() over-reading of ETH_SS_STATS

2021-06-30T12:47:00Z

[ Upstream commit da5ac772cfe2a03058b0accfac03fad60c46c24d ] In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. The memcpy() is copying the entire structure, not just the first array. Adjust the source argument so the compiler can do appropriate bounds checking. Signed-off-by: Kees Cook Signed-off-by: David S.

r8169: don't advertise pause in jumbo mode

2021-04-14T20:05:40Z

It has been reported [0] that using pause frames in jumbo mode impacts performance. There's no available chip documentation, but vendor drivers r8168 and r8125 don't advertise pause in jumbo mode. So let's do the same, according to Roman it fixes the issue.

r8169: fix DMA being used after buffer free if WoL is enabled

2021-03-21T02:01:41Z

IOMMU errors have been reported if WoL is enabled and interface is brought down. It turned out that the network chip triggers DMA transfers after the DMA buffers have been freed. For WoL to work we need to leave rx enabled, therefore simply stop the chip from being a DMA busmaster.

r8169: fix jumbo packet handling on RTL8168e

Josef reported [0] that using jumbo packets fails on RTL8168e. Aligning the values for register MaxTxPacketSize with the vendor driver fixes the problem.

net: phy: rename PHY_IGNORE_INTERRUPT to PHY_MAC_INTERRUPT

2021-02-15T23:20:49Z

Some internal PHY's have their events like link change reported by the MAC interrupt. We have PHY_IGNORE_INTERRUPT to deal with this scenario. I'm not too happy with this name. We don't ignore interrupts, typically there is no interrupt exposed at a PHY level. So let's rename it to PHY_MAC_INTERRUPT. This is in line with phy_mac_interrupt(), which is called from the MAC interrupt handler to handle PHY events.
