+Subject: [PATCH 1/3] sfc: Fix SFE4002 initialisation
+
+From: Steve Hodgson <shodgson at solarflare.com>
+
+Commit 357d46a17e54c9a87e0e6ef3930ff4ab2d232b81 "sfc: QT202x: Remove
+unreliable MMD check at initialisation" broke initialisation of the
+SFE4002.  efx_mdio_reset_mmd() returns a positive value rather than 0
+on success.  The above commit causes this value to be propagated up
+by qt202x_reset_phy(), which is treated as a failure by its callers.
+Change qt202x_reset_phy() to return 0 if successful.
+
+The PCI layer treats >0 as "fail, but please call remove() anyway",
+which means that unloading the driver would cause a crash.  Add a
+WARN_ON() on the failure path of efx_pci_probe() to provide early
+warning if there are any other cases where we do this.

+Subject: [PATCH 2/3] sfc: Fix sign of efx_mcdi_poll_reboot() error in efx_mcdi_poll()
+
+efx_mcdi_poll() uses positive error numbers, matching the MCDI
+protocol.  It must negate the result of efx_mcdi_poll_reboot() which
+returns the usual negative error numbers.

+Subject: [PATCH 3/3] sfc: SFE4002/SFN4112F: Widen temperature and voltage tolerances
+
+The temperature and voltage limits currently set on these boards are
+too conservative and will cause the driver to stop the net device
+erroneously in some systems.
+
+Based on a review of the chip datasheets and advice from the designer
+of these boards:
+
+- Raise the maximum board temperatures to the specified maximum ambient
+  temperatures for their PHYs plus the expected temperature bias of the
+  board
+- Raise the maximum controller temperature to 90 degrees
+- Lower the minimum temperatures to 0 degrees
+- Widen the voltage tolerances to at least +/- 10%
