net/davinci_emac: fix failing PHY connect attempts PHY connect attempts fail if no PHY id is specified in the emac platform data and another mdio bus has been registered before 'davinci_mdio' bus. In this case when configuring the interface, there will be an attempt to connect to already attached PHY on the previously registered mdio bus: net eth1: PHY already attached net eth1: could not connect to phy smsc911x-0:01 IP-Config: Failed to open eth1 IP-Config: Device `eth1' not found Fix this by modifying match_first_device() to match first PHY device on 'davinci_mdio' bus.

davinci_emac: Do not free all rx dma descriptors during init This patch fixes a regression that was introduced by commit 0a5f38467765ee15478db90d81e40c269c8dda20 davinci_emac: Add Carrier Link OK check in Davinci RX Handler Said commit adds a check whether the carrier link is ok. If the link is not ok, the skb is freed and no new dma descriptor added to the rx dma channel. This causes trouble during initialization when the carrier status has not yet been updated. If a lot of packets are received while netif_carrier_ok returns false, all dma descriptors are freed and the rx dma transfer is stopped. The bug occurs when the board is connected to a network with lots of traffic and the ifconfig down/up is done, e.g., when reconfiguring the interface with DHCP. The bug can be reproduced by flood pinging the davinci board while doing ifconfig eth0 down ifconfig eth0 up on the board. After that, the rx path stops working and the overrun value reported by ifconfig is counting up. This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20 and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.

davinci_emac: use eth_hw_addr_random() instead of random_ether_addr() Use eth_hw_addr_random() instead of calling random_ether_addr() to set addr_assign_type correctly to NET_ADDR_RANDOM. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. Remove one memcpy from emac_dev_setmac_addr() since this is a duplicate: it's already done some lines above. v2: use bitops, adapt to eth_hw_addr_random, remove a memcpy Signed-off-by: Danny Kukawka <danny.kukawka@bisect.de> Signed-off-by: David S.

net/davinci: do not use all descriptors for tx packets The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half. Tested on a custom board using nmap / ping -f to the board from two different hosts. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>
