2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny1-5/+5
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.

2011-04-11netxen: limit skb frags for non tso packetamit salecha2-2/+19
Machines are getting deadlock in four node cluster environment. All nodes are accessing (find /gfs2 -depth -print|cpio -ocv > /dev/null) 200 GB storage on a GFS2 filesystem. This result in memory fragmentation and driver receives 18 frags for 1448 byte packets. For non tso packet, fw drops the tx request, if it has >14 frags. Fixing it by pulling extra frags.

2011-03-30drivers/net: Remove IRQF_SAMPLE_RANDOM flag from network driversJavier Martinez Canillas1-1/+1
The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed. Every input point to the kernel's entropy pool have to better document the type of entropy source it is. drivers/char/random.c now implements a set of interfaces that can be used for devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced with these add_*_randomness exported functions. Network drivers are not a good source of entropy. They use as a source of entropy essentially a remote host. Which means that the source of entropy can be potentially controlled by an attacker. Also, with heavy workloads the entropy decreases due to less hardware interrupts happening thanks to irq mitigation and NAPI. If a system relies in its network interface as a entropy source it has a false sense of security. Systems that don't have devices whose drivers are good sources of entropy, should either use a hardware random number generator or feed the kernel's entropy pool from userspace using other sources of entropy such as EGD, video_entropyd, timer_entropyd and audio-entropyd.

2011-03-27net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka1-1/+1
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem).

2010-11-28netxen: avoid using reset_devices as it may become obsoleteRajesh Borundia1-2/+4
In kdump environment do not depend on reset_devices parameter to reset the device as the parameter may become obsolete. Instead use an adapter specific mechanism to determine if the device needs a reset. Driver maintains a count of number of pci functions probed and decrements the count when remove handler of that pci function is called. If the first probe, probe of function 0, detects the count as non zero then reset the device.
