net: dsa: add error handling for pskb_trim_rcsum

2018-06-25T23:53:53+00:00

[ Upstream commit 349b71d6f427ff8211adf50839dbbff3f27c1805 ] When pskb_trim_rcsum fails, the lack of error-handling code may cause unexpected results. This patch adds error-handling code after calling pskb_trim_rcsum. Signed-off-by: Zhouyang Jia Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

net: dsa: Do not register devlink for unused ports

2018-05-25T14:46:02+00:00

[ Upstream commit 5447d78623da2eded06d4cd9469d1a71eba43bc4 ] Even if commit 1d27732f411d ("net: dsa: setup and teardown ports") indicated that registering a devlink instance for unused ports is not a problem, and this is true, this can be confusing nonetheless, so let's not do it.

net: dsa: Discard frames from unused ports

2018-04-12T10:29:59+00:00

[ Upstream commit fc5f33768cca7144f8d793205b229d46740d183b ] The Marvell switches under some conditions will pass a frame to the host with the port being the CPU port. Such frames are invalid, and should be dropped. Not dropping them can result in a crash when incrementing the receive statistics for an invalid port.

net: dsa: Fix dsa_is_user_port() test inversion

2018-03-13T01:04:55+00:00

During the conversion to dsa_is_user_port(), a condition ended up being reversed, which would prevent the creation of any user port when using the legacy binding and/or platform data, fix that.

net: dsa: Support internal phy on 'cpu' port

2018-01-24T00:22:38+00:00

This adds support for enabling the internal PHY for a 'cpu' port. It has been tested on GE B850v3, B650v3 and B450v3, which have a built-in MV88E6240 switch hardwired to a PCIe based network card. On these machines the internal PHY of the i210 network card and the Marvell switch are connected to each other and must be enabled for properly using the switch. While the i210 PHY will be enabled when the network interface is enabled, the switch's port is not exposed as network interface. Additionally the mv88e6xxx driver resets the chip during probe, so the PHY is disabled without this patch. Signed-off-by: Sebastian Reichel Reviewed-by: Florian Fainelli Signed-off-by: David S.

net: dsa: Move padding into Broadcom tagger

2018-01-05T16:21:31+00:00

Instead of having the different master network device drivers potentially used by DSA/Broadcom tags, move the padding necessary for the switches to accept short packets where it makes most sense: within tag_brcm.c. This avoids multiplying the number of similar commits to e.g: bgmac, bcmsysport, etc. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: Fix dsa_legacy_register() return value

2018-01-03T02:52:48+00:00

We need to make the dsa_legacy_register() stub return 0 in order for dsa_init_module() to successfully register and continue registering the ETH_P_XDSA packet handler.

net: dsa: mediatek: combine MediaTek tag with VLAN tag

2017-12-15T15:31:54+00:00

In order to let MT7530 switch can recognize well those egress packets having both special tag and VLAN tag, the information about the special tag should be carried on the existing VLAN tag. On the other hand, it's unnecessary for extra handling for ingress packets when VLAN tag is present since it is able to put the VLAN tag after the special tag and then follow the existing way to parse.
