+Subject: [PATCH 01/12] net: thunderx: use proper interface type for RGMII
+
+The configuration of the OCTEONTX XCV_DLL_CTL register via
+xcv_init_hw() is such that the RGMII RX delay is bypassed
+leaving the RGMII TX delay enabled in the MAC:
+
+ /* Configure DLL - enable or bypass
+ * TX no bypass, RX bypass
+ */
+ cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL);
+ cfg &= ~0xFF03;
+ cfg |= CLKRX_BYP;
+ writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL);
+
+This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID
+and not PHY_INTERFACE_MODE_RGMII.
+
+Fixing this allows RGMII PHY drivers to do the right thing (enable
+RX delay in the PHY) instead of erroneously enabling both delays in the
+PHY.

+Subject: [PATCH 02/12] net: thunderx: workaround BGX TX Underflow issue
+
+While it is not yet understood why a TX underflow can easily occur
+for SGMII interfaces resulting in a TX wedge. It has been found that
+disabling/re-enabling the LMAC resolves the issue.

+Subject: [PATCH 03/12] can: mcp251x: convert to half-duplex SPI
+
+Some SPI host controllers such as the Cavium Thunder do not support
+full-duplex SPI. Using half-duplex transfers allows the driver to work
+with those host controllers.
