2023-05-23igb: Always copy ethernet headerAkihiko Odaki1-20/+23
igb_receive_internal() used to check the iov length to determine copy the iovs to a contiguous buffer, but the check is flawed in two ways: - It does not ensure that iovcnt > 0. - It does not take virtio-net header into consideration. The size of this copy is just 22 octets, which can be even less than the code size required for checks. This (wrong) optimization is probably not worth so just remove it.

Before this change, e1000 and the common code updated BPRC and MPRC depending on the matched filter, but e1000e and igb decided to update those counters by deriving the packet type independently. This inconsistency caused a multicast packet to be counted twice. Updating BPRC and MPRC depending on are fundamentally flawed anyway as a filter can be used for different types of packets. For example, it is possible to filter broadcast packets with MTA. Always determine what counters to update by inspecting the packets.

This reverts commit b320e21c48ce64853904bea6631c0158cc2ef227, which accidentally broke TCG, because it made the TCG -cpu max report the presence of MTE to the guest even if the board hadn't enabled MTE by wiring up the tag RAM. This meant that if the guest then tried to use MTE QEMU would segfault accessing the non-existent tag RAM: ==346473==ERROR: UndefinedBehaviorSanitizer: SEGV on unknown address (pc 0x55f328952a4a bp 0x00000213a400 sp 0x7f7871859b80 T346476) ==346473==The signal is caused by a READ memory access. ==346473==Hint: this fault was caused by a dereference of a high value address (see register values below).
