2011-08-02r8169 : MAC address change fix for the 8168e-vl.françois romieu1-0/+27
Addresses https://bugzilla.kernel.org/show_bug.cgi?id=39252 Hayes suggested that the usual MAC{0, 4} register writes be completed with writes to extended GigaMAC registers : - 0xe0 .. 0xe5 - 0xf2 .. 0xf7 Registers 0xf0 and 0xf1 should be set to 0.

2011-07-28r8169: Add support for D-Link 530T rev C1 (Kernel Bug 38862)Lennart Sorensen1-0/+1
The D-Link DGE-530T rev C1 is a re-badged Realtek 8169 named DLG10028C, unlike the previous revisions which were skge based. It is probably the same as the discontinued DGE-528T (0x4300) other than the PCI ID. The PCI ID is 0x1186:0x4302. Adding it to r8169.c where 0x1186:0x4300 is already found makes the card be detected and work.

All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com> Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem.

2011-05-09r8169: remove non-NAPI context invocation of rtl8169_rx_interrupt.Francois Romieu1-23/+9
Invocation of rtl8169_rx_interrupt from rtl8169_reset_task was originally intended to retrieve as much packets as possible from the rx ring when a reset was needed. Nowadays rtl8169_reset_task is only scheduled, with some delay a. from the tx timeout watchdog b. when resuming c. from rtl8169_rx_interrupt itself It's dubious that the loss of outdated packets will matter much for a) and b). c) does not need to call itself again.

2011-05-09r8169: link speed selection timer rework.Francois Romieu1-35/+9
The implementation was a bit krusty. The 10s rtl8169_phy_timer timer has been (was ?) required with older 8169 for adequate phy operation when full gigabit is advertised in autonegotiated mode. The timer does nothing if the link is up. Otherwise it keeps resetting the phy until things improve. - the device private data field phy_1000_ctrl_reg was used to schedule the timer. Avoid it and save a few bytes. - rtl8169_set_settings pending timer is disabled before changing the link settings as rtl8169_phy_timer is not always needed (see the removed test in rtl8169_phy_timer). - rtl8169_set_speed the requested link parameters may not match the chipset : bail out early on failure. - rtl8169_open Calling rtl8169_request_timer is redundant with -> rtl8169_open -> rtl8169_init_phy -> rtl8169_set_speed -> mod_timer The latter always enables the phy timer whereas the former did not for RTL_GIGA_MAC_VER_01. It should not make things worse but only time will tell if reality agrees. - rtl8169_request_timer : unused yet. Removed. - rtl8169_delete_timer : useless. Bloat. Removed. Side effect : the timer may kick in if the TBI is enabled. I do not know if the TBI has ever been used in real life.

2011-05-09r8169: rtl8169_set_speed_xmii cleanup.Francois Romieu1-10/+1
Shorten chipset version test. No functional change. Careful readers will notice that the 'supports_gmii' flag is deduced from the device PCI id. Though less specific than the chipset related RTL_GIGA_MAC_VER_XY, it is good enough to detect a GMII deprieved 810x. Some features push for a device specific configuration (improved jumbo frame support for instance). 'supports_gmii' will follow this path if / when the device PCI id test stops working.

2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny1-1/+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.

2011-04-24r8169: don't request firmware when there's no userspace.François Romieu1-28/+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.

2011-04-18r8169: TSO fixes.Francois Romieu1-72/+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.
