net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5}

2015-04-17T00:13:18+00:00

[ Upstream commit 87f966d97b89774162df04d2106c6350c8fe4cb3 ] On a MIPS Malta board, tons of fifo underflow errors have been observed when using u-boot as bootloader instead of YAMON. The reason for that is that YAMON used to set the pcnet device to SRAM mode but u-boot does not. As a result, the default Tx threshold (64 bytes) is now too small to keep the fifo relatively used and it can result to Tx fifo underflow errors. As a result of which, it's best to setup the SRAM on supported controllers so we can always use the NOUFLO bit. Cc: Cc: Cc: Cc: Don Fry Signed-off-by: Markos Chandras Signed-off-by: David S.

amd-xgbe: Fix napi Rx budget accounting

2014-10-22T21:50:31+00:00

Currently the amd-xgbe driver increments the packets processed counter each time a descriptor is processed. Since a packet can be represented by more than one descriptor incrementing the counter in this way is not appropriate. Also, since multiple descriptors cause the budget check to be short circuited, sometimes the returned value from the poll function would be larger than the budget value resulting in a WARN_ONCE being triggered. Update the polling logic to properly account for the number of packets processed and exit when the budget value is reached. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Properly handle feature changes via ethtool

2014-10-22T21:50:31+00:00

The ndo_set_features callback function was improperly using an unsigned int to save the current feature value for features such as NETIF_F_RXCSUM. Since that feature is in the upper 32 bits of a 64 bit variable the result was always 0 making it not possible to actually turn off the hardware RX checksum support. Change the unsigned int type to the netdev_features_t type in order to properly capture the current value and perform the proper operation. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

am2150: Update nmclan_cs.c to use update PCMCIA API

2014-09-22T18:27:44+00:00

Resolves compile warning about use of a deprecated function call: drivers/net/ethernet/amd/nmclan_cs.c: In function ‘nmclan_config’: drivers/net/ethernet/amd/nmclan_cs.c:624:3: warning: ‘pcmcia_request_exclusive_irq’ is deprecated (declared at include/pcmcia/ds.h:213) [-Wdeprecated-declarations] ret = pcmcia_request_exclusive_irq(link, mace_interrupt); Updates pcmcia_request_exclusive_irq() to pcmcia_request_irq().

ethernet: amd: use pr_info_once()

2014-09-12T22:02:41+00:00

It will use pr_info_one() to print the version info of the driver in probe function only once. No need to use the static variable here. Signed-off-by: Varka Bhadram Signed-off-by: David S. Miller

amd-xgbe: Enable interrupts for all management counters

2014-09-06T05:37:30+00:00

As the management counters reach a threshold they will generate an interrupt so the value can be saved and the counter reset. The current code does not enable this interrupt on all counters. This can result in inaccurate statistics. Update the code to enable all the counters to generate an interrupt when its threshold is exceeded. Signed-off-by: Tom Lendacky Signed-off-by: David S.

amd-xgbe: Treat certain counter registers as 64 bit

2014-09-06T05:37:30+00:00

Even if the management counters are configured to be 32 bit register values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are always 64 bit counter registers. Since they are not being treated as 64 bit values, these statistics are being reported incorrectly (ifconfig, ethtool, etc.). Update the routines used to read the registers to access the "hi" register (an offset of 4 from the "lo" register) to create a 64 bit value for these 64 bit counters.

amd-xgbe: Fix initialization of the wrong spin lock

During allocation and initialization of the network driver structures, the wrong pointer is used to initialize a spin lock. Fix the spin lock initialization by using the proper pointer. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller
