I came accross this item on both the 2084 and 2094 PSP buckets:
06/12/13 The TCP Segmentation Off-load feature (also called OSA
Large Send) is enabled by default if all of the
requirements documented in PK02490 are met. Due to the
potential for OSAs that are using this feature to
experience unrecoverable INOPs(requiring intervention
by configuring the affected CHPIDs off-line), it is
currently recommended that Segmentation Off-load be
disabled. To disable Segmentation Offload, it is
recommended that the following maintenance be applied
and then code NOSEGMENTATIONOFFLoad on the
GLOBALCONFIG statement in the TCPIP PROFILE.

Once all of the microcode issues for Segmentation
Offload are resolved, a Washington Systems Center
Flash will be released advising what the minimum
recommended code level will be. Flash 1232599 on
the z/OS Communications Server Support web page
will also be updated at that time; to subscribe
