            Bug ID: 268352
           Summary: bnxt(4) can't re-use a leaf
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me

         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: sdalu@sdalu.com

When loading bnxt(4) driver, numerous warning are displayed (sysctl) as well as
some failure (BAR0 mapping, IFDI_ATTACH_PRE)

~~~

Nevertheless the device seems to be working 
(I haven't try heavy load or complex configuration yet)

Also perhaps related to the above errors, renaming interface in rc.conf using
ifconfig_xxx_name, fails to have it's ip address configured later in rc.conf

Failing example:
ifconfig_bnxt0_name="net0"
ifconfig_net0="inet aaa.bbb.ccc.ddd/24"


But the following works
ifconfig_bnxt0="inet aaa.bbb.ccc.ddd/24 name net0"
