manual abstract
lan3 current values:
New Transmit Flow Control = Off
•
Attempting to turn on Rx flow control for a Flex-10 interface on which the MTU size is greater
than 1500 (enabling Jumbo Frames) brings up the warning message shown in the following
example. The Rx flow control cannot be turned on in this instance, so the specified value (on)
is invalid; Rx flow control remains turned off.
server2#nwmgr -s -A rx_fctrl=on -c lan3
WARNING: For flex10 interface, the Rx flow control is always on
For non-flex10 interface, if Jumbo MTU is set, the rx flow control cannot be turned on
lan3 current values:
New Receive Flow Control = ERROR: Invalid value

Table 3 HP-UX 11i v3 September 2012 fixes — 10GigEthr-02 B.11.31.1209
SR number
Description
QXCR1001202586
The host encountered a rare hang situation as the intctl command gets stuck within the
kernel after repeated interrupt migrations are run on the host backing interface. The cause is
the driver failing to perform an appropriate handshake with the kernel module responsible
for completing the interrupt migration event under certain rare circumstances.
Problems fixed in recent versions
Table 4 HP-UX 11i v3 May 2012 Fixes — 10GigEthr-02 B.11.31.1205
SR number
Description
QXCR1001209171
AVIO: High outbound discards on HPVM guest with iexgbe interface. TCP connections (such
as rlogin and telnet) from a remote system to the guest do not work and the guest hangs
intermittently.
QXCR1001182096
When packets with an invalid LLC, IP or TCP header length are sent through the HPVM guest
igssn interface, the iexgbe driver will drop such packets. But the guest is not aware of
such drops and it continues to expect send completion for those packets. This situation results
in a gradual reduction of the number of usable descriptors for igssn, which causes
performance to degrade and, eventually, the igssn interface to hang.
QXCR1001192266
For non-Flex-10 (non-VC) interfaces, when using customized iexgbe configuration file settings
that enable Jumbo Frames (MTU size greater than 1500), problems occur at startup. This
problem surfaced after Tx and Rx flow control support was introduced to the iexgbe driver
(QXCR1001093086). The workaround in the preceding release was to disable flow control
by default. The B.11.31.1205 release sets Tx and Rx flow control to ON by default. Any
request to turn on Jumbo Frames will override the Rx flow control settings and automatically
set Rx flow control to OFF.

Description
QXCR1001192266
Disables flow control by default. This removes the possibility of bringing up issues introduced
with the B.11.31.1201 release (QXCR1001093086). For more information about the issues,
see Section 4 (page 8).
Table 6 HP-UX 11i v3 September 2011 Fixes — 10GigEthr-02 B.11.31.1109
SR number
Description
QXCR1001017249
When a port of the device is reset while there is traffic on any of the ports, the reset operation
might result in a failure to run down the adapter that can only be recovered by rebooting the
system.
