Hi, We are running into a situation where rsp_prod index in the shared ring is not getting updated for the netfront tx ring by the netback. We see that rsp_cons is the same value as rsp_prod, with req_prod 236 slots away(tx ring is full). From looking at the netfront driver code, it looks as if xennet_tx_buf_gc processing only happens if rsp_prod is more than rsp_cons. Our understanding is that netfront...

Hi All, I am sure this has been answered somewhere in the list in the past, but I can''t find it. I was wondering if the linux guest netfront driver has GRO support in it. tcpdump shows packets coming in with 1500 bytes, although the eth0 in dom0 and the vif corresponding to the linux guest in dom0 is showing that they receive large packet: In dom0: eth0 Link encap:Ethernet HWaddr 90:E2:BA:3A:B1:A4 UP BROADCAST RUNNING...

Hi Keir: [LINUX] netfront: Cleanup and fix TSO/GSO/CHECKSUM conditionals This patch tries to minimise the amount of code that is conditionally compiled. This is desirable (and the Linux way) as it helps to prevent people breaking code unwittingly since conditionals may hide compile problems. It also adds a missing condit...

This function is in fact counting the ring slots required for responses. Separate the concepts of ring slots and skb frags make the code clearer, as now netfront and netback can have different MAX_SKB_FRAGS, slot and frag are not mapped 1:1 any more.

__initcall is for things which are always built into the kernel. Kconfig says netfront is tristate (although without a module_exit, the module won''t be unloadable).
