[Qemu-devel] [PULL v2 06/12] e1000: Fixing the received/transmitted packets' counters

From: Leonid Bloch According to Intel's specs, these counters (as the other Statistic registers) stick at 0x when this maximal value is reached. Previously, they would reset after the max. value. Signed-off-by: Leonid Bloch

[Qemu-devel] [PULL v2 08/12] e1000: Fixing the packet address filtering procedure

From: Leonid Bloch Previously, if promiscuous unicast was enabled, a packet was received straight away, even if it was a multicast or a broadcast packet. This patch fixes that behavior, while making the filtering procedure a bit more human-readable.

[Qemu-devel] [PULL v2 05/12] e1000: Trivial implementation of various MAC registers

From: Leonid Bloch These registers appear in Intel's specs, but were not implemented. These registers are now implemented trivially, i.e. they are initiated with zero values, and if they are RW, they can be written or read by the driver, or read only if they are

[Qemu-devel] [PULL v2 03/12] e1000: Add support for migrating the entire MAC registers' array

From: Leonid Bloch This patch makes the migration of the entire array of MAC registers possible during live migration. The entire array is just 128 KB long, so practically no penalty should be felt when transmitting it, additionally to the previously transmitted

[Qemu-devel] [PULL v2 07/12] e1000: Fixing the received/transmitted octets' counters

From: Leonid Bloch Previously, these 64-bit registers did not stick at their maximal values when (and if) they reached them, as they should do, according to the specs. This patch introduces a function that takes care of such registers, avoiding code duplication,
