Bug ID: 230465
Summary: ixl: not working in netmap mode
Product: Base System
Version: 11.2-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: bugs at FreeBSD.org

Hello!
I have a ixl NIC (chip=0x15728086 'Ethernet Controller X710 for 10GbE SFP+) and
I'm trying to work with netmap.
When I was compiling kernel with ixl support I have errors with missing
reference of: "'ixl_rx_miss', 'ixl_rx_miss_bufs and 'ixl_crcstrip'" so then I
modify ixl_txrx.c and added this references like this:
#ifdef DEV_NETMAP
#include <dev/netmap/if_ixl_netmap.h>
int ixl_rx_miss = 0, ixl_rx_miss_bufs = 0, ixl_crcstrip = 1;
#endif /* DEV_NETMAP */
When I did this my kernel was compiled with sucess and now I see ixl interfaces
in "ifconfig" command.
Then now I'm trying netmap on then, but seems not working. In my application on
top of netmap I see "dmesg" like this:

Using pkt-get from netmap github I'm able to receive packets but not able to
transmit then like this:

Then "dmesg" show:
