Now that the network stack can handle inbound packets with partial checksums, we should no longer clobber the ip_summed field in the loopback driver. This is because CHECKSUM_UNNECESSARY implies that the checksum field is actually valid which is not true for loopback packets since it's only partial (and thus complemented). This allows packets from lo to then be SNATed to an external source while still preserving the checksum's validity. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

skb_gso_segment didn't preserve some attributes in the original skb such as the netfilter fields. This was harmless until they were used which is the case for packets going through lo. This patch makes it call __copy_skb_header which also picks up some other missing attributes. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

This patch enables TSO since the loopback device is naturally capable of handling packets of any size. This also means that we won't enable GSO on lo which is good until GSO is fixed to preserve netfilter state as netfilter treats loopback packets in a special way.

Ethtool stats are 64-bits in length. net_device_stats members are unsigned long types. When gathering information for a get_ethtool_stats call, the driver will call a driver-private, inlined get_stat64() function, which returns an unsigned long value. This call will inadvertently mask off the upper 32-bits of a stat on 32-bit machines. This patch defines a new get_estat() inline function and modifies the ESTAT_ADD() macro to use it.

The git commit 7c5026aa ("tg3: Add link state reporting to UMP firmware") introduced code that waits for previous firmware events to be serviced before attempting to submit a new event. Unfortunately that patch contained a bug that cause the driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended. This patch fixes that bug. This bug revealed that not all firmware versions service driver events though. Since we do not know which versions of the firmware do and don't service these events, the driver needs some way to minimize the effects of the delay. This patch solves the problem by recording a jiffies timestamp when it submits an event to the hardware. If the jiffies counter shows that 2.5 milliseconds have already passed, a wait is not needed and the driver can proceed to submit a new event.

The ENABLE_ASF flag is set when DASH is enabled on the NIC, but DASH does not run on the RX CPU. Instead it runs on the APE. Consequently, the driver does not need to send "driver alive" updates to the RX CPU when the APE is present.

If the driver resets the chip while the APE is performing a register access, that register access will never complete and the APE will hang indefinitely. To prevent this race condition, the driver must acquire an APE mutex before resetting the chip. The APE will not attempt a register access until it acquires this lock.

Let me first state that disabling the route cache hash rebuild should not be done without extensive analysis on the risk profile and careful deliberation. However, there are times when this can be done safely or for testing. For example, when you have mechanisms for ensuring that offending parties do not exist in your network. This patch lets the user disable the rebuild if the interval is set to zero. This also incidentally fixes a divide-by-zero error with name-spaces. In addition, this patch makes the effect of an interval change immediate rather than it taking effect at the next rebuild as is currently the case.

In certain cases when ASF or other management firmware is running, the chip may be configured to always strip out the VLAN tag even when VLAN acceleration is not enabled. This causes some VLAN tagged packets to be received by the host stack without any knowledge that the original packet was VLAN tagged. We fix this by re-inserting the VLAN tag into the packet when necessary.
