10GigEthr-02 (iexgbe) B.11.31.1306 Ethernet Driver Release Notes

Firmware update completed
Updated firmware will be active after a system reboot
• Boot time reduced significantly for configurations requiring that multiple parameters be set
(QXCR1001149267)
The boot time configuration delay when multiple parameters are being set is now reduced
significantly. Prior to this release, system boot time could be impacted significantly by the
number of parameters being set in the configuration file, especially in system configurations
supporting a large number of iexgbe LAN devices. Each configuration parameter was set
using independent calls to the driver. Additional delays would result if driver resets were
required for the settings to take effect. With this release of the driver, a single call is used to
set multiple parameters, reducing the delay caused by multiple resets.
A new command line option has been added to the lanadmin command to provide this
enhancement:
lanadmin -X boot_parameter [{drv_pr_on | drv_pr_off}] [mtu=size] [{recv_cko_on | recv_cko_off}] [{send_cko_on
| send_cko_off}] [drv_mq=queue-number] [vmtu={0 | 32160}] ppa
For example:
/usr/sbin/lanadmin -X boot_param send_cko_on drv_mq=4 vmtu=32160
recv_cko_on drv_pr_off mtu=1500 9
2.2 Changed features
The iexgbe driver has been enhanced with performance and stability improvements.
2.2.1 Changes introduced with 10GigEthr-02 B.11.31.1205
Tx and Rx flow control are now enabled by default. This flow control feature (which is optional)
has certain limitations documented in Section 4 (page 11).
Table 1 (page 7) lists the Rx and Tx flow control settings and defaults, as determined by the MTU
setting.
