An implementation of a code generator for BPF programs to speed up packet filtering on PPC64, inspired by Eric Dumazet's x86-64 version. Filter code is generated as an ABI-compliant function in module_alloc()'d mem with stackframe & prologue/epilogue generated if required (simple filters don't need anything more than an li/blr). The filter's local variables, M[], live in registers. Supports all BPF opcodes, although "complicated" loads from negative packet offsets (e.g. SKF_LL_OFF) are not yet supported. There are a couple of further optimisations left for future work; many-pass assembly with branch-reach reduction and a register allocator to push M[] variables into volatile registers would improve the code quality further. This currently supports big-endian 64-bit PowerPC only (but is fairly simple to port to PPC32 or LE!). Enabled in the same way as x86-64: echo 1 > /proc/sys/net/core/bpf_jit_enable Or, enabled with extra debug output: echo 2 > /proc/sys/net/core/bpf_jit_enable Signed-off-by:

Otherwise, the firmware will not respond and we'll have to wait for timeout. Refactor the wait loop we already have into a separate function for this purpose. Signed-off-by:

Newer VPD datablocks can exceed the size the tg3 driver is traditionally used to. This can cause some of the routines that operate on the VPD data to fail when in-fact they could have succeeded had they known the correct size. This patch fixes the problem. Signed-off-by:

This patch fixes interrupt selftest failures for recent devices (57765, 5717, 5718. 5719, 5720) by disabling MSI one-shot mode and applying the status tag workaround to the selftest code. Signed-off-by:

Occasionally, when the network cable is removed after a successful autonegotiation, the device will not send a link down interrupt to the driver. This happens because of a bad interaction of an EEE workaround. The fix is to adjust the code so that the root cause condition does not happen. Signed-off-by:

This patch increases the scope of the EEE interoperability workaround to include more asic revisions. The workarond value is tuned to workaround a link flap issue at 100Mbps. Signed-off-by:

Commit f2096f94, entitled "tg3: Add 5720 H2BMC support", needed to add code to preserve some bits set by firmware. Unfortunately the new code causes throughput to stop after a chip reset because it enables state machines before they are ready. This patch undoes the problematic code. The bits will be restored later in the init sequence. Signed-off-by:

This patch fixes both the failure in the self-test on 578xx and a hole in a parity recovery flow that this failure has discovered: - internal 'pending' state in a VLAN_MAC object wasn't been cleared when the object state change was called with DRV_ONLY flag, which in particular happens when a parity error happens during the self-test. - bp->sp_state wasn't cleared in the similar circumstances as described above.

Fix the parity errors recovery flow for 578xx: - Add a separate column for the 578xx in the parity mask registers DB. - Fix the bnx2x_process_kill_chip_reset() to handle the blocks newly introduced in the 578xx. Cover ATC and PGLUE_B blocks for 57712 and 578xx. Signed-off-by: -

If overlapping networks with different interfaces was added to the set, the type did not handle it properly. Example ipset create test hash:net,iface ipset add test 192.168.0.0/16,eth0 ipset add test 192.168.0.0/24,eth1 Now, if a packet was sent from 192.168.0.0/24,eth0, the type returned a match. In the patch the algorithm is fixed in order to correctly handle overlapping networks. Limitation: the same network cannot be stored with more than 64 different interfaces in a single set.
