--- Comment #1 from mkashani@nvidia.com (mkashani@nvidia.com) ---
Hi,=20
Sorry for the late response,

**Root Cause**: MLX5 hardware/firmware steering on root table (group 0) has
limited support for jump actions combined with partial MAC address masks. T=
he
bonding PMD directly passes the flow to slave ports without adaptation.

## Immediate Workarounds

### Workaround 1: Use Group 1 (Recommended)
Instead of group 0, use group 1:

```bash
flow create 2 group 1 priority 0 ingress pattern eth dst spec 01:00:00:00:0=
0:00
dst mask 01:00:00:00:00:00 / end actions jump group 2 / end
```

First, create a catch-all rule in group 0 to reach group 1:
```bash
flow create 2 group 0 priority 1 ingress pattern eth / end actions jump gro=
up 1
/ end
```
