Netmap could not allocate memory : netmap_config_obj_allocator requested objsize 140032 out of range [256, 131072]

[elite12monkey]

env: FreeBSD 14.0 current ( just 1 week old on this day )
system has 8GB RAM with ZFS
card IXGBE 550 T2 with 8 hw queues
processor: i5 6500 , 4 cores ( this processor has no hyper threading)

i am new to github and please pardon me for any mistakes. Excellent project and thanks for putting it into open-source domain.
I have some good experience at C programming and is facing an abnormal situation. I am interested in only packet capture ( no TX required).
my app cannot guarantee that it will be be able to poll the fd as fast as possible. ( due to unavoidable reasons, latencies for POLL can be upto 10 ms/milliseconds between successive polls)

also note that i am requesting 16384 extra bufs per ring to implement ZC, in Arg3

default netmap comes with rxd size 2048,
if i change the rxds using the setting in /boot/loader.conf
dev.ix.0.iflib.override_nrxds="4096"
and start my app i get the following messages
kernel: 754.834915 [ 852] iflib_netmap_config txr 4 rxr 4 txd 2048 rxd 4096 rbufsz 2048
kernel: 754.835050 [1026] netmap_obj_malloc netmap_ring request size 65792 too large
kernel: 754.835061 [2001] netmap_mem2_rings_create Cannot allocate RX_ring

since default ring in freeBSD is around 38000

sysctl dev.netmap.ring_size=69000
and restarting application, it works fine

Till above everything is fine.
However, i have patched the ixgbe driver in freebsd to allow max nrxds from 4096 to 32768
after compiling kernel and all, i set this in /boot/loader.conf to have 8192 descriptors

dev.ix.0.iflib.override_nrxds="8192"

at this point, all networking etc ( non netmap things ) are working fine.
now when i start the my app the following kernel messages comes,

kernel: 076.863860 [ 852] iflib_netmap_config txr 4 rxr 4 txd 2048 rxd 8192 rbufsz 2048
kernel: 076.864016 [1026] netmap_obj_malloc netmap_ring request size 131328 too large
kernel: 076.864027 [2001] netmap_mem2_rings_create Cannot allocate RX_ring

at this point, netmap tells me ring size is less, just like the above case, so i set it like this
sysctl dev.netmap.ring_size=139000

however, now when i start the app, the get the following messages.
kernel: 267.695175 [1347] netmap_config_obj_allocator aligning object by 32 bytes
kernel: 267.695187 [1352] netmap_config_obj_allocator requested objsize 140032 out of range [256, 131072]

i have checked netmap source code, and figured out the following limits

netmap/sys/dev/netmap/netmap_mem2.c

Line 551 in bd5813a

.objmaxsize = 32*PAGE_SIZE,

which states that 32*4096 = 131072

after patching netmap and increasing max size, everything works great.
so my question is can it be controlled via sysctl or should i patch this into source code i maintain.

also note that i updated the max size of object in object pool.
Can you please provide a sysctl for freebsd ( or other platforms ) to control max_size of ring and max size of object in your allocator pools or whether it could be linked to existing sysctls ( this way we do not need new sysctls and existing sysctl will get the job done.)
for eg.
if dev.netmap.ring_size is greater than max size of ring pool, then automatically increase the max limit of pool.

same can be done with object pool,
if ____ is greater than max size of ring pool, then automatically increase the max object size of pool

Thank you.
