istgt or iscsi_target with 4k drive

Hello,

I'm trying to setup istgt or iscsi_target with a GELI encrypted device. The problem is that the drive is a 4K sector drive.

Code: 
# geli list
Geom name: ada1p3.eli
State: ACTIVE
EncryptionAlgorithm: AES-XTS
KeyLength: 128
Crypto: software
UsedKey: 0
Flags: NONE
KeysAllocated: 698
KeysTotal: 698
Providers:
1. Name: ada1p3.eli
   Mediasize: 2995224162304 (2.7T)
   Sectorsize: 4096
   Mode: r0w0e0
Consumers:
1. Name: ada1p3
   Mediasize: 2995224166400 (2.7T)
   Sectorsize: 512
   Stripesize: 4096
   Stripeoffset: 0
   Mode: r1w1e1

I'm getting errors with both:
Code:

I know the problem is the sector size, because trying with a testfile works.
Code: 
Geom name: md0.eli
State: ACTIVE
EncryptionAlgorithm: AES-XTS
KeyLength: 128
Crypto: software
UsedKey: 0
Flags: NONE
KeysAllocated: 1
KeysTotal: 1
Providers:
1. Name: md0.eli
   Mediasize: 524287488 (500M)
   Sectorsize: 512
   Mode: r0w0e0
Consumers:
1. Name: md0
   Mediasize: 524288000 (500M)
   Sectorsize: 512
   Mode: r1w1e1
With md0.eli they both start up fine. How do I tell one of the two that the drive is a 4K one?
Thanks.
