-Subject: [PATCH] net: bgmac: connect to PHY even if it is BGMAC_PHY_NOREGS
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Recent bgmac change was meant to just fix a race between "Generic PHY"
-and "bcm53xx" drivers after -EPROBE_DEFER. It modified bgmac to use
-phy_connect() only if there is a real PHY device connected.
-
-That change broke bgmac on bcm47xx. bcma_phy_connect() now registers a
-fixed PHY with the bgmac_phy_connect_direct(). That fails as another
-fixed PHY (also using address 0) is already registered - by bcm47xx arch
-code bcm47xx_register_bus_complete().
-
-This change brings origial behaviour. It connects Ethernet interface
-with pseudo-PHY (switch device) and adjusts Ethernet interface link to
-match connected switch.
-
-This fixes:
-[ 2.548098] bgmac_bcma bcma0:1: Failed to register fixed PHY device
-[ 2.554584] bgmac_bcma bcma0:1: Cannot connect to phy
-
-Fixes: b5375509184d ("net: bgmac: improve handling PHY")
-Link: https://lore.kernel.org/netdev/3639116e-9292-03ca-b9d9-d741118a4541@gmail.com/T/#u

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-bgmac allocates new replacement buffer before handling each received
-frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU
-time. Ideally bgmac should just respect currently set MTU but it isn't
-the case right now. For now just revert back to the old limited frame
-size.
-
-This change bumps NAT masquarade speed by ~95%.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If SoC has a CardBus we can set resources of device at slot 1 only. It's
-impossigle to set bridge resources as it simply overwrites device 1
-configuration and usually results in Data bus error-s.

+Subject: [PATCH] net: bgmac: connect to PHY even if it is BGMAC_PHY_NOREGS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Recent bgmac change was meant to just fix a race between "Generic PHY"
+and "bcm53xx" drivers after -EPROBE_DEFER. It modified bgmac to use
+phy_connect() only if there is a real PHY device connected.
+
+That change broke bgmac on bcm47xx. bcma_phy_connect() now registers a
+fixed PHY with the bgmac_phy_connect_direct(). That fails as another
+fixed PHY (also using address 0) is already registered - by bcm47xx arch
+code bcm47xx_register_bus_complete().
+
+This change brings origial behaviour. It connects Ethernet interface
+with pseudo-PHY (switch device) and adjusts Ethernet interface link to
+match connected switch.
+
+This fixes:
+[ 2.548098] bgmac_bcma bcma0:1: Failed to register fixed PHY device
+[ 2.554584] bgmac_bcma bcma0:1: Cannot connect to phy
+
+Fixes: b5375509184d ("net: bgmac: improve handling PHY")

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+bgmac allocates new replacement buffer before handling each received
+frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU
+time. Ideally bgmac should just respect currently set MTU but it isn't
+the case right now. For now just revert back to the old limited frame
+size.
+
+This change bumps NAT masquarade speed by ~95%.

+Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If SoC has a CardBus we can set resources of device at slot 1 only. It's
+impossigle to set bridge resources as it simply overwrites device 1
+configuration and usually results in Data bus error-s.
