Current GRO can hold packets in gro_list for almost unlimited time, in case napi->poll() handler consumes its budget over and over. In this case, napi_complete()/napi_gro_flush() are not called. Another problem is that gro_list is flushed in non friendly way : We scan the list and complete packets in the reverse order. (youngest packets first, oldest packets last) This defeats priorities that sender could have cooked. Since GRO currently only store TCP packets, we dont really notice the bug because of retransmits, but this behavior can add unexpected latencies, particularly on mice flows clamped by elephant flows. This patch makes sure no packet can stay more than 1 ms in queue, and only in stress situations. It also complete packets in the right order to minimize latencies.

Currently, we terminate the eeprom access through clearing the CS by: RTL_W8 (Cfg9346, ~EE_CS); or writeb (~EE_CS, ee_addr); This would left the eeprom into "Config. Register Write Enable:" state which is not expcted as the highest two bits were set to 0x11 ( expected is the "Normal" mode (0x00)). Solving this by write 0x0 instead of ~EE_CS when terminating the eeprom access. Signed-off-by: NJason Wang <jasowang@redhat.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We set intr mask before its handler is registered, this does not work well when 8139cp is sharing irq line with other devices. As the irq could be enabled by the device before 8139cp's hander is registered which may lead unhandled irq. Fix this by introducing an helper cp_irq_enable() and call it after request_irq().

I am not family with RealTek RTL-8139C+ series 10/100 PCI Ethernet driver. I try to guess the meaning of RxProtoIP and IPFail. RxProtoIP stands for received IPv4 packet that upper protocol is not tcp and udp. !(status & IPFail) is true means that driver correctly to check checksum in IPv4 header. If these are right, driver will set ip_summed with CHECKSUM_UNNECESSARY for other upper protocol, e.g. sctp, igmp protocol. This will cause protocol stack ignores checksum check for packets with invalid checksum. This patch is only compile-test. Signed-off-by: NShan Wei <shanwei@cn.fujitsu.com> Signed-off-by: NDavid S.

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.

This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
