net: bcmgenet: Software reset EPHY after power on

2015-12-09T19:34:07Z

[ Upstream commit 5dbebbb44a6ad94aab2cd1a46f7676f255403f64 ] The EPHY on GENET v1->v3 is extremely finicky, and will show occasional failures based on the timing and reset sequence, ranging from duplicate packets, to extremely high latencies. Perform an additional software reset, and re-configuration to make sure it is in a consistent and working state.

bcm63xx_enet: check 1000BASE-T advertisement configuration

2015-10-21T13:36:38Z

If a gigabit ethernet PHY is connected to a fast ethernet MAC, then it can detect 1000 support from the partner but not use it. This results in a forced speed of 1000 and RX/TX failure. Check for 1000BASE-T support and then check the advertisement configuration before setting the MAC speed to 1000mbit. Signed-off-by: Simon Arlott Signed-off-by: David S. Miller

net: bcmgenet: Fix early link interrupt enabling

2015-10-19T06:07:12Z

Link interrupts are enabled in init_umac(), which is too early for us to process them since we do not yet have a valid PHY device pointer. On BCM7425 chips for instance, we will crash calling phy_mac_interrupt() because phydev is NULL. Fix this by moving the link interrupts enabling in bcmgenet_netif_start(), under a specific function: bcmgenet_link_intr_enable() and while at it, update the comments surrounding the code.

bnx2x: Prevent UDP 4-tuple configurations on older adapters

2015-10-11T12:09:30Z

Configuring 4-tuple RSS hsahing for UDP [E.g., by using `ethtool -N rx-flow-hash udp4 sdfn'] on a 57710/57711 adapter would cause it to assert as HW does not support such a configuration. Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

bnx2x: byte swap rss_key to comply to Toeplitz specs

2015-09-24T21:34:49Z

After a good amount of debugging, I found bnx2x was byte swaping the 40 bytes of rss_key. If we byte swap the key, then bnx2x generates hashes matching MSDN specs as documented in (Verifying the RSS Hash Calculation) https://msdn.microsoft.com/en-us/library/windows/hardware/ff571021% 28v=vs.85%29.aspx It is mostly a non issue, unless we want to mix different NIC in a host, and want consistent hashing among all of them, ie if they all use the boot time generated rss key, or if some application is choosing specific tuple(s) so that incoming traffic lands into known rx queue(s).

net: bcmgenet: Fix module autoload for OF platform driver

2015-09-21T23:08:21Z

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt Acked-by: Florian Fainelli Signed-off-by: David S. Miller

bnx2x: track vxlan port count

2015-09-18T05:32:16Z

The callback for adding vxlan port can be called with the same port for both IPv4 and IPv6. Do not disable the offloading when the same port for both protocols is added and later one of them removed. Signed-off-by: Jiri Benc Signed-off-by: David S. Miller

bnx2x: use ktime_get_seconds() for timestamp

2015-09-11T22:02:59Z

commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the bnx2x_update_mfw_dump() function that reads the current time and stores it in a 32-bit field that gets passed into a buffer in a fixed format. This is potentially broken when the epoch overflows in 2038, and otherwise overflows in 2106. As we're trying to avoid uses of struct timeval for this reason, I noticed the addition of this function, and tried to rewrite it in a way that is more explicit about the overflow and that will keep working once we deprecate struct timeval. I assume that it is not possible to change the ABI any more, otherwise we should try to use a 64-bit field for the seconds right away.

bgmac: Update fixed_phy_register()

2015-09-02T18:39:58Z

Commit a5597008dbc2 ("phy: fixed_phy: Add gpio to determine link up/down.") added a new argument to fixed_phy_register(), but missed to update bgmac driver, causing the following build failure: drivers/net/ethernet/broadcom/bgmac.c:1450:2: error: too few arguments to function 'fixed_phy_register' Add the missing argument.
