* net: cosmetic: Fix var naming net <-> eth driversJoe Hershberger2015-04-181-2/+2
| | | | | | | | | | | | | | | Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support. This patch has a few remaining checkpatch.pl failures that would be out of the scope of this patch to fix (drivers that are in gross violation of checkpatch.pl).

* net: cpsw: am335x: Drop constant link checking from rx/tx path'sStefan Roese2014-08-281-18/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We noticed on the DXR2 platform (AM335x with a SMSC LAN9303 switch connected to the CPSW MAC) that the network performance in U-Boot is quite poor. Only when the transfer is started without a cable connected, and the cable is plugged after the first timeout "T" occured, an increased in performance can be seen. Debugging has revealed, that the cpsw driver has constant link checking builtin into the rx and tx functions. This results in the bad performance and seems to be unnecessary. The link has already been checked in the init function, before the transfer is started. This usually is sufficient. BTW: I have seen no other network driver in U-Boot so far, that constantly checks for link in the rx / tx functions. The performance numbers on the DXR2 board are: 0.56 MiB/s cpsw_check_link() in rx and tx path 0.87 MiB/s cpsw_check_link() only in tx path 1.0 MiB/s cpsw_check_link() only in rx path 2.7 MiB/s no cpsw_check_link() in rx and tx path So with this patch the network performance on DXR2 increases from 0.56 to 2.7 MiB/s (nearly 5 times as fast).

* drivers: net: cpsw: add support to have phy address from cpsw platform dataMugunthan V N2014-03-041-2/+2
| | | | | | | | | | | | Some platforms like AM437x have different EVMs with different phy addresses, so this patch adds support for passing phy address via cpsw plaform data. Also renamed phy_id to phy_addr so better understanding of the code.

* am335x: cpsw: optimize cpsw_recv to increase network performanceVladimir Koutny2013-12-041-1/+1
| | | | | | | | | | | | In 48ec5291, only TX path was optimized; this does the same also for RX path. This results in huge increase of TFTP throughput on custom am3352 board (from 312KiB/s to 1.8MiB/s) and eliminates occasional transfer timeouts.

* net, phy, cpsw: fix gigabit register accessHeiko Schocher2013-07-301-1/+1
| | | | | | | | | | | | | accessing a lan9303 switch with the cpsw driver results in wrong speed detection, as the switch sets the BMSR_ERCAP in BMSR register, and follow read of the MII_STAT1000 register fails, as the switch does not support it. Current code did not check, if a phy_read() fails ... fix this.
