82599 10 GbE Controller—Errata

Workaround:

This issue is resolved by the 82599 EEPROM Dev Starter rev 4.22 or newer.

Status: B0=Yes; NoFix

56 ETS Resolution

Problem:

IEEE802.1Qaz specification, aka Enhanced Transmission Selection (ETS) for Bandwidth Sharing

Between Traffic Classes, requires ETS resolution of 1% with max allowed deviation of +/- 10% of link

bandwidth.

ETS resolution is defined as the minimum percent of link bandwidth that can be allocated to a specific

traffic class.

In the 82599, if 9.5 KB Jumbo Frames are enabled, the ETS resolution is 12.5%. If 9.5 KB Jumbo

Frames are disabled, ETS resolution is 3.3%.

Implication:

ETS bandwidth allocation limitation and specification conformance.

Workaround:

None.

Status: B0=Yes; NoFix

57 Flow Control and Missed Packets Counters

Limitation

Problem:

When performing back-to-back registers read accesses, the following counters might retrieve an

incorrect value:

RXMPC[n], LXONTXC, LXOFFTXC, PXONTXC[n], PXOFFTXC[n].

Implication:

Incorrect statistics collection.

Workaround:

Add one microsecond delay before/after these registers access.

Status: B0=Yes; NoFix
