* ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated. Tested: make allyesconfig on x86_64 + e1000e/bnx2x work Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ethtool: Use full 32 bit speed range in ethtool's set_settingsDavid Decotigny2011-04-291-1/+2
| | | | | | | | | | | | This makes sure the ethtool's set_settings() callback of network drivers don't ignore the 16 most significant bits when ethtool calls their set_settings(). All drivers compiled with make allyesconfig on x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * r8169: don't request firmware when there's no userspace.François Romieu2011-04-241-28/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware is cached during the first successfull call to open() and released once the network device is unregistered. The driver uses the cached firmware between open() and unregister_netdev(). So far the firmware is optional : a failure to load the firmware does not prevent open() to success. It is thus necessary to 1) unregister all 816x / 810[23] devices and 2) force a driver probe to issue a new firmware load.

* | r8169: TSO fixes.Francois Romieu2011-04-181-72/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - the MSS value is actually contained in a 11 bits wide (0x7ff) field. The extra bit in the former MSSMask did encompass the TSO command bit ("LargeSend") as well (0xfff). Oops. - the Tx descriptor layout is not the same through the whole chipset family. The 8169 documentation, the 8168c documentation and Realtek's drivers (8.020.00, 1.019.00, 6.014.00) highlight two layouts: 1. 8169, 8168 up to 8168b (included) and 8101 2. {8102e, 8168c} and beyond - notwithstanding the "first descriptor" and "last descriptor" bits, the same Tx descriptor content is enforced when a packet consists of several descriptors. The chipsets are documented to require it. Credits go to David Dillow <dave@thedillows.org> for the original patch.

| | | | | | | | | | | | | | | | | | | | Some experiment-based action to prevent my 8168 chipsets locking-up hard in the irq handler under load (pktgen ~1Mpps). Apparently a reset is not always mandatory (is it at all ?). - RTL_GIGA_MAC_VER_12 - RTL_GIGA_MAC_VER_25 Missed ~55% packets. Note: - this is an old SiS 965L motherboard - the 8168 chipset emits (lots of) control frames towards the sender - RTL_GIGA_MAC_VER_26 The chipset does not go into a frenzy of mac control pause when it crashes yet but it can still be crashed.
