* Add appropriate <linux/prefetch.h> include for prefetch usersPaul Gortmaker2011-05-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After discovering that wide use of prefetch on modern CPUs could be a net loss instead of a win, net drivers which were relying on the implicit inclusion of prefetch.h via the list headers showed up in the resulting cleanup fallout. Give them an explicit include via the following $0.02 script. ========================================= #!/bin/bash MANUAL="" for i in `git grep -l 'prefetch(.*)' .` ; do grep -q '<linux/prefetch.h>' $i if [ $? = 0 ] ; then continue fi ( echo '?^#include <linux/?a' echo '#include <linux/prefetch.h>' echo . echo w echo q ) | ed -s $i > /dev/null 2>&1 if [ $? != 0 ]; then echo $i needs manual fixup MANUAL="$i $MANUAL" fi done echo ------------------- 8\<---------------------- echo vi $MANUAL ========================================= Signed-off-by: Paul <paul.gortmaker@windriver.com> [ Fixed up some incorrect #include placements, and added some non-network drivers and the fib_trie.c case - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-291-2/+2
| | | | | | | | | | | | | | | | | | | | 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>

| * bna: fix for clean fw re-initializationRasesh Mody2011-04-144-15/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a kernel crash, bna control path state machine and firmware do not get a notification and hence are not cleanly shutdown. The registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to hang during kdump kernel boot. This patch, during the initialization of first PCI function, resets corresponding register when unclean shutown is detect by reading chip registers. This will make sure that ioc/fw gets clean re-initialization. Signed-off-by: Debashis Dutt <ddutt@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

Similarly for 'cmd_h' in bna_mbox_flush_q and the entirety of bna_rit_mod_uninit() is unused since variables are purely set but no action is made using them. Same for 'bna' in bna_rit_create() and 'ret' in bna_rx_create(). Just kill them off. Signed-off-by: David S. Miller <davem@davemloft.net>

* vlan: Don't check for vlan group before vlan_tx_tag_present.Jesse Gross2010-10-211-1/+1
| | | | | | | | | | | | | Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.
