(cherry picked from commit 3f2b9607756d0f92ca29c844db0718b313a06634) 2024-02-19T04:47:16Z Warner Losh imp@FreeBSD.org 2024-02-05T05:43:49Z urn:sha1:a9600913b4dbf66fb257ea90702ea4705fb40362 Some platforms require an adjustment of the ethernet hearders. Rather than make this be on __NO_STRICT_ALIGNMENT being defined, define VTNET_ETHER_ALIGN to be either 0 or ETHER_ALIGN (aka 2). Add a test to the if statements to only do them when != 0. This eliminates the #ifdef sprinkled in the code, still communicates the intent and gives the same compiled results.

This leads to a situation where we might fail if the mtu is close to a bucket size (say 2018) such that the added padding would push us over the edge for a full-sized packet. mtu of 2018 is super rare (2016 and 2020 would both work), but fix it none-the-less. It's a shame we can't just set VTNET_RX_HEADER_PAD to 2 in this case. The 4 seems hard-coded somewhere I've not found documented (I think it's in the protocol given the comments about VIRTIO_F_ANY_LAYOUT).

We do this on allocation (and when we check the length of the mbufs in the lro_nomrg case). We can't just adjust the clustersz in the softc, because it's also used to allocate the mbufs and it needs to be the proper size for that. Since we otherwise use the size of the mbuf (or sometimes the smaller size of the received packet) to compute how much we can buffer, this ensures no overflows. The 2 byte adjustment also does not affect how many packets we can receive in the lro_nomrg case.
