Known issue. As part of creating a jail you default network interface will be added to a bridge. When the member interface is added to a bridge if_bridge will remove capabilities for that jail the other members do not have.
We added a checkbox to disable offload capabilities for selected interfaces to avoid the interruption.

You can also specify another network interface for the jail if you don't want to disable offload for the chelsio.

In some situations, having a jail running can cause errors with Chelsio NICs at boot, and subsequently. Confirmed on 11.3-U2:
At boot (appears immediately after console menu displayed):
tso4 disabled due to -txcsum
tso6 disabled due to -txcsum
bridge0: error setting capabilities on cxgbe0: 35
When attempt made to remedy using ifconfig:
ifconfig cxgbe0 rxcsum txcsum tso lro
ifconfig: tso: Resource temporarily unavailable
Now reported/confirmed by multiple users, including multiple confirms that not booting (or deleting) the jail resolves the issue.
