+Subject: [PATCH] net: phy: Introduce QUSGMII PHY mode
+
+The QUSGMII mode is a derivative of Cisco's USXGMII standard. This
+standard is pretty similar to SGMII, but allows for faster speeds, and
+has the build-in bits for Quad and Octa variants (like QSGMII).
+
+The main difference with SGMII/QSGMII is that USXGMII/QUSGMII re-uses
+the preamble to carry various information, named 'Extensions'.
+
+As of today, the USXGMII standard only mentions the "PCH" extension,
+which is used to convey timestamps, allowing in-band signaling of PTP
+timestamps without having to modify the frame itself.
+
+This commit adds support for that mode. When no extension is in use, it
+behaves exactly like QSGMII, although it's not compatible with QSGMII.

+Subject: [PATCH] net: phy: Add 1000BASE-KX interface mode
+
+Add 1000BASE-KX interface mode. This 1G backplane ethernet as described in
+clause 70. Clause 73 autonegotiation is mandatory, and only full duplex
+operation is supported.
+
+Although at the PMA level this interface mode is identical to
+1000BASE-X, it uses a different form of in-band autonegation. This
+justifies a separate interface mode, since the interface mode (along
+with the MLO_AN_* autonegotiation mode) sets the type of autonegotiation
+which will be used on a link. This results in more than just electrical
+differences between the link modes.
+
+With regard to 1000BASE-X, 1000BASE-KX holds a similar position to
+SGMII: same signaling, but different autonegotiation. PCS drivers
+(which typically handle in-band autonegotiation) may only support
+1000BASE-X, and not 1000BASE-KX. Similarly, the phy mode is used to
+configure serdes phys with phy_set_mode_ext. Due to the different
+electrical standards (SFI or XFI vs Clause 70), they will likely want to
+use different configuration. Adding a phy interface mode for
+1000BASE-KX helps simplify configuration in these areas.

+Subject: [PATCH] net: phy: Add support for rate matching
+
+This adds support for rate matching (also known as rate adaptation) to
+the phy subsystem. The general idea is that the phy interface runs at
+one speed, and the MAC throttles the rate at which it sends packets to
+the link speed. There's a good overview of several techniques for
+achieving this at [1]. This patch adds support for three: pause-frame
+based (such as in Aquantia phys), CRS-based (such as in 10PASS-TS and
+2BASE-TL), and open-loop-based (such as in 10GBASE-W).
+
+This patch makes a few assumptions and a few non assumptions about the
+types of rate matching available. First, it assumes that different phys
+may use different forms of rate matching. Second, it assumes that phys
+can use rate matching for any of their supported link speeds (e.g. if a
+phy supports 10BASE-T and XGMII, then it can adapt XGMII to 10BASE-T).
+Third, it does not assume that all interface modes will use the same
+form of rate matching. Fourth, it does not assume that all phy devices
+will support rate matching (even if some do). Relaxing or strengthening
+these (non-)assumptions could result in a different API. For example, if
+all interface modes were assumed to use the same form of rate matching,
+then a bitmask of interface modes supportting rate matching would
+suffice.
+
+For some better visibility into the process, the current rate matching
+mode is exposed as part of the ethtool ksettings. For the moment, only
+read access is supported. I'm not sure what userspace might want to
+configure yet (disable it altogether, disable just one mode, specify the
+mode to use, etc.). For the moment, since only pause-based rate
+adaptation support is added in the next few commits, rate matching can
+be disabled altogether by adjusting the advertisement.
+
+802.3 calls this feature "rate adaptation" in clause 49 (10GBASE-R) and
+"rate matching" in clause 61 (10PASS-TL and 2BASE-TS). Aquantia also calls
+this feature "rate adaptation". I chose "rate matching" because it is
+shorter, and because Russell doesn't think "adaptation" is correct in this
+context.
