https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188369 --- Comment #7 from miguelmclara@gmail.com --- Dunno if this will help in anyway... I lack C skills and I certainly don't know much about the Xen code... In anycase I will post my findings: I decided to compare the changes on 9 and 10, because 9 is working for me. I noticed that warning comes from netfront.c: if (txr->status != NETIF_RSP_OKAY) { printf("%s: WARNING: response is %d!\n", __func__, txr->status); } So I decided to try and find out whats "NETIF_RSP_OKAY", which apears to "come from" sys/xen/interface/io/netif.h This is the diff from 9 to 10 (stable) src, could any of this changes be the cause!? % diff -u sys/xen/interface/io/netif.h /tmp/netif.h --- sys/xen/interface/io/netif.h 2014-04-11 01:41:58.000000000 +0100 +++ /tmp/netif.h 2015-01-31 06:42:58.000000000 +0000 @@ -41,7 +41,7 @@ /* * This is the 'wire' format for packets: * Request 1: netif_tx_request -- NETTXF_* (any flags) - * [Request 2: netif_tx_extra] (only if request 1 has NETTXF_extra_info) + * [Request 2: netif_tx_extra] (only if request 1 has NETTXF_extra_info) * [Request 3: netif_tx_extra] (only if request 2 has XEN_NETIF_EXTRA_FLAG_MORE) * Request 4: netif_tx_request -- NETTXF_more_data * Request 5: netif_tx_request -- NETTXF_more_data @@ -173,6 +173,10 @@ #define _NETRXF_extra_info (3) #define NETRXF_extra_info (1U<<_NETRXF_extra_info) +/* GSO Prefix descriptor. */ +#define _NETRXF_gso_prefix (4) +#define NETRXF_gso_prefix (1U<<_NETRXF_gso_prefix) + struct netif_rx_response { uint16_t id; uint16_t offset; /* Offset in page of start of received packet */ -- You are receiving this mail because: You are the assignee for the bug.
