This change removes UDP from the supported protocols for RSS hashing.  The
reason for removing this protocol is because IP fragmentation was causing a
network flow to be broken into two streams, one for fragmented, and one for
non-fragmented and this in turn was causing out-of-order issues.

igb: Use only a single Tx queue in SR-IOV mode

The 82576 expects the second rx queue in any pool to receive L2 switch
loop back packets sent from the second tx queue in another pool.  The
82576 VF driver does not enable the second rx queue so if the PF driver
sends packets destined to a VF from its second tx queue then the VF
driver will never see them.  In SR-IOV mode limit the number of tx queues
used by the PF driver to one. This patch fixes a bug reported in which
the PF cannot communciate with the VF and should be considered for 2.6.34

x86: Drop CONFIG_MCORE2 check around setting of NET_IP_ALIGN

This patch removes the CONFIG_MCORE2 check from around NET_IP_ALIGN.  It is
based on a suggestion from Andi Kleen.  The assumption is that there are
not any x86 cores where unaligned access is really slow, and this change
would allow for a performance improvement to still exist on configurations
that are not necessarily optimized for Core 2.

Anton Vorontsov [Wed, 30 Jun 2010 06:39:15 +0000]
gianfar: Implement workaround for eTSEC-A002 erratum

MPC8313ECE says:

"If the controller receives a 1- or 2-byte frame (such as an illegal
 runt packet or a packet with RX_ER asserted) before GRS is asserted
 and does not receive any other frames, the controller may fail to set
 GRSC even when the receive logic is completely idle. Any subsequent
 receive frame that is larger than two bytes will reset the state so
 the graceful stop can complete. A MAC receiver (Rx) reset will also
 reset the state."

This patch implements the proposed workaround:

"If IEVENT[GRSC] is still not set after the timeout, read the eTSEC
 register at offset 0xD1C. If bits 7-14 are the same as bits 23-30,
 the eTSEC Rx is assumed to be idle and the Rx can be safely reset.
 If the register fields are not equal, wait for another timeout
 period and check again."

Anton Vorontsov [Wed, 30 Jun 2010 06:39:13 +0000]
gianfar: Implement workaround for eTSEC76 erratum

MPC8313ECE says:

"For TOE=1 huge or jumbo frames, the data required to generate the
 checksum may exceed the 2500-byte threshold beyond which the controller
 constrains itself to one memory fetch every 256 eTSEC system clocks.

 This throttling threshold is supposed to trigger only when the
 controller has sufficient data to keep transmit active for the duration
 of the memory fetches. The state machine handling this threshold,
 however, fails to take large TOE frames into account. As a result,
 TOE=1 frames larger than 2500 bytes often see excess delays before start
 of transmission."

This patch implements the workaround as suggested by the errata
document, i.e.:

"Limit TOE=1 frames to less than 2500 bytes to avoid excess delays due to
 memory throttling.
 When using packets larger than 2700 bytes, it is recommended to turn TOE
 off."

To be sure, we limit the TOE frames to 2500 bytes, and do software
checksumming instead.

Anton Vorontsov [Wed, 30 Jun 2010 06:39:12 +0000]
gianfar: Implement workaround for eTSEC74 erratum

MPC8313ECE says:

"If MACCFG2[Huge Frame]=0 and the Ethernet controller receives frames
 which are larger than MAXFRM, the controller truncates the frames to
 length MAXFRM and marks RxBD[TR]=1 to indicate the error. The controller
 also erroneously marks RxBD[TR]=1 if the received frame length is MAXFRM
 or MAXFRM-1, even though those frames are not truncated.
 No truncation or truncation error occurs if MACCFG2[Huge Frame]=1."

There are two options to workaround the issue:

"1. Set MACCFG2[Huge Frame]=1, so no truncation occurs for invalid large
 frames. Software can determine if a frame is larger than MAXFRM by
 reading RxBD[LG] or RxBD[Data Length].

 2. Set MAXFRM to 1538 (0x602) instead of the default 1536 (0x600), so
 normal-length frames are not marked as truncated. Software can examine
 RxBD[Data Length] to determine if the frame was larger than MAXFRM-2."

This patch implements the first workaround option by setting HUGEFRAME
bit, and gfar_clean_rx_ring() already checks the RxBD[Data Length].

9 years agoe1000e: don't inadvertently re-set INTX_DISABLE
Dean Nelson [Tue, 29 Jun 2010 18:12:05 +0000]
e1000e: don't inadvertently re-set INTX_DISABLE

Should e1000_test_msi() fail to see an msi interrupt, it attempts to
fallback to legacy INTx interrupts. But an error in the code may prevent
this from happening correctly.

Before calling e1000_test_msi_interrupt(), e1000_test_msi() disables SERR
by clearing the SERR bit from the just read PCI_COMMAND bits as it writes
them back out.

Upon return from calling e1000_test_msi_interrupt(), it re-enables SERR
by writing out the version of PCI_COMMAND it had previously read.

The problem with this is that e1000_test_msi_interrupt() calls
pci_disable_msi(), which eventually ends up in pci_intx(). And because
pci_intx() was called with enable set to 1, the INTX_DISABLE bit gets
cleared from PCI_COMMAND, which is what we want. But when we get back to
e1000_test_msi(), the INTX_DISABLE bit gets inadvertently re-set because
of the attempt by e1000_test_msi() to re-enable SERR.

The solution is to have e1000_test_msi() re-read the PCI_COMMAND bits as
part of its attempt to re-enable SERR.

During debugging/testing of this issue I found that not all the systems
I ran on had the SERR bit set to begin with. And on some of the systems
the same could be said for the INTX_DISABLE bit. Needless to say these
latter systems didn't have a problem falling back to legacy INTx
interrupts with the code as is.
